Ionic or molecular compound calculator

This problem demonstrates how to predict the molecular formulas of ionic compounds. First, look at the locations of the elements on the periodic table. Atoms in the same column as each other group tend to exhibit similar characteristics, including the number of electrons the elements would need to gain or lose to resemble the nearest noble gas atom. To determine common ionic compounds formed by elements, keep the following in mind:.

When you write the formula for an ionic compound, remember that the positive ion is always listed first. Write down the information you have for the usual charges of the atoms and balance them to answer the problem. The charges listed above for atoms within groups are the common chargesbut you should be aware that the elements sometimes take on different charges.

See the table of the valences of the elements for a list of the charges that the elements have been known to assume. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert.

Predict the formulas of the ionic compounds formed by the following elements:.

Group 6 ions nonmetals have -2 charges. Group 7 ions halides have -1 charges. There is no simple way to predict the charges of the transition metals. Look at a table listing charges valences for possible values.In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.

The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. Individual ions within an ionic compound usually have multiple nearest neighbours, so are not considered to be part of molecules, but instead part of a continuous three-dimensional network, usually in a crystalline structure.

Ionic compounds without these ions are also known as salts and can be formed by acid—base reactions. Ionic compounds can also be produced from their constituent ions by evaporation of their solvent, precipitation, freezing, a solid-state reaction, or the electron transfer reaction of reactive metals with reactive non-metals, such as halogen gases. Ionic compounds typically have high melting and boiling points, and are hard and brittle.

As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized. Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. Together, they form a neutral compound because the ions balance each other out. This is true for all ionic compounds — the positive and negative charges must be in balance.

Potassium oxide, or K2O, is another example of an ionic compound. You may have noticed that unlike the sodium chloride example, which has one sodium ion for each chlorine ion, this time there are two potassium atoms for each oxygen. This is because the charges have to be balanced for the ionic compound.

All you have to do to determine how many of each ion will be in the compound is take a quick look at the periodic table. Sodium is in the first column of the periodic table, so it will lose one electron. Chlorine is in the second-to-last column, so it will gain one electron. Each atom in this ionic compound will lose or gain one electron, so they can pair up in a one-to-one ratio.

In its purest form, ionic bonding is not directional. It can be regarded as simple positive-negative Coulombic attraction between point charges. This is different from covalent bonding, in which electrons are shared by atoms, forming directional bonds.

However, absolutely pure ionic bonding does not exist. There is always at least a small degree of covalent bonding character in ionic compounds. Q: State whether the following statement is true or false.

Sodium Chloride has a higher melting point than Magnesium Oxide. Justify your answer. The following statement is True. In an ionic compound, such as common salt, NaCl, or magnesia MgO, the formula tells us the correct ratio of elements present, but it does not specify the unit. Each crystal contains an unspecified number of ions: the numbers are enormous: even a 0.

A binary ionic compound is composed of ions of two different elements — one of which is a metal, and the other a nonmetal.This form calculates the bond polarity by comparing the electronegativity of two atoms. Chemical Bond Polarity Calculator. Choose the first element:. Calculating, please wait When two atoms bond to form a molecule, the electron s in the bond are not necessarily shared equally.

By comparing the Electronegativity of the two atoms See the Periodic Table for a list of Electronegativitesone can determine if the bond is Ionic one atom takes the electron from the other atom in the bondPolar Covalent the electron is shared, but it is spends most of its time near the atom with higher electronegativityor nonpolar covalent the electron is shared between both atoms equally.

Notes on Electronegativity: Electronegativity is the ability of an atom within a molecule to pull electrons away from a binding partner another atom in the molecule. If the difference is between.

Empirical Formula & Molecular Formula Determination From Percent Composition

For example, in HCl, the bond is covalent, but the shared electron spends most of its time closer to the Cl atom than the H atom, forming a dipole If the difference is less than. For example, Cl-Cl is a perfectly covalent bond since both partners have the same electronegativity Electronegativity increases as one travels within a Period from left to right in the Periodic Table.

Electronegativity decreases as one traverses a group column from top to bottom in the Periodic Table. Flourine F is the most electronegative element; in a molecule, it will try to pull the binding electrons from other atoms in the molecule towards itself.

If two atoms have a large difference in electronegativites, a large amount of energy will be released upon forming the bond. If two atoms have a small difference in electronegativities, the energy released on formation of the bond will be small.If we can't tunnel through the Earth, how do we know what's at its center?

They will also be present in the same number on both sides of the equation.A comparative study of what ionic compounds and molecular compounds are will help you understand the differences between the two of them.

A compound is formed when two or more elements go on to combine together to form a new substance. The chemical and physical properties of the compound that is eventually formed are different from those of the constituent elements. Most of the substances found in nature exist in the form of compounds, rather than as free elements. There are less than a hundred different elements that can be found in nature, but the compounds that they form are actually found in millions.

When an atom loses or gains one or more electrons, it becomes positively or negatively charged, and this charged atom is called an ion. Ions are unstable, and hence, a negatively charged ion gets attracted towards a positively charged ion to form an ionic compound.

Difference Between Ionic and Molecular Compounds

The bonds that they form are called ionic bonds. If an atom loses an electron, it acquires a positive charge, and if it gains an electron, it acquires a negative charge. A common example of an ionic compound is common salt or NaCl, in which the sodium atom gains one pair of electrons from the chlorine atom, and forms an ionic bond.

Other compounds like NaBr sodium bromideKCl potassium chlorideand CaCl 2 calcium chloride are also ionic compounds. Molecular compounds are also called covalent compounds. In these compounds, the atoms of the elements share one or more electrons between them.

The bonds that are formed as a result of the sharing of electrons are called covalent bonds. Equal sharing of electrons between the atoms results into non-polar bonding, whereas unequal sharing results into polar bonds. A common example of a molecular compound is water or H 2 O, in which the hydrogen and oxygen atoms share a pair of electrons between them, thus forming covalent bonds.

Ionic Compounds: Ionic compounds are usually in the solid state at standard temperature and pressure STP. This is due to the strong attraction between their positively charged and negatively charged ions.

They form a crystalline structure called crystal lattice. Molecular Compounds: They usually exist in the liquid or gaseous state at standard temperature and pressure. This is because of a weak force of attraction between the atoms forming covalent bonds. Ionic Compounds: Due to the strong attractive forces between the positive and negative ions in an ionic compound, a lot of energy is required to break the ionic bonds between the oppositely charged ions. So they have a high melting and boiling point.

Molecular Compounds: Due to a weak force of attraction between the atoms, these compounds usually have a low melting and boiling point. Ionic Compounds: Ionic compounds are very hard because of their closely-packed lattice structure and the ionic bonds between the charged ions. They are very brittle, and it is difficult to bend them. Molecular Compounds: The solid forms of molecular compounds are generally very soft and brittle.

The covalent bonds in such compounds are flexible, and bend or break easily. Ionic Compounds: In their solid state, ionic compounds do not conduct electricity. But when melted in an aqueous solution, they act as strong electrolytes and conduct electricity. Molecular Compounds: They are poor conductors of electricity and heat.

When they dissolve in an aqueous solution, they still remain in their molecular form. Due to lack of free ions, they do not carry electric charge very well, and thus, act as poor conductors of electricity.In ordinary chemical reactions, the nucleus of each atom and thus the identity of the element remains unchanged.

Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. You can use the periodic table to predict whether an atom will form an anion or a cation, and you can often predict the charge of the resulting ion.

Atoms of many main-group metals lose enough electrons to leave them with the same number of electrons as an atom of the preceding noble gas.

For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table. For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons.

A discussion of the theory supporting the favored status of noble gas electron numbers reflected in these predictive rules for ion formation is provided in a later chapter of this text. Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number.

Moving from the far right to the left on the periodic table, elements often form anions with a negative charge equal to the number of groups moved left from the noble gases. This trend can be used as a guide in many cases, but its predictive value decreases when moving toward the center of the periodic table.

In fact, transition metals and some other metals often exhibit variable charges that are not predictable by their location in the table.

Some elements exhibit a regular pattern of ionic charge when they form ions. An ion found in some compounds used as antiperspirants contains 13 protons and 10 electrons. What is its symbol? Because the number of protons remains unchanged when an atom forms an ion, the atomic number of the element must be Knowing this lets us use the periodic table to identify the element as Al aluminum.
