or both. As with simple ionic compounds, these compounds must also be electrically neutral, so their formulas can be predicted by treating the polyatomic ions as discrete units. We use parentheses in a formula to indicate a group of atoms that behave as a unit. For example, the formula for...
Formulas of Ionic Compounds Yesterday we talked about what all of the numbers and symbols in chemical formulas mean, and today we’re going to start to talk about what the names of these formulas are. The first class of compounds that we’ll talk about will be ionic ...

A:The chemical formula represents the formula of ionic compounds, whereas the molecules formula represents the formula of covalent compounds. For example- Table salt has a chemical formula because it is made up of \({\rm{N}}{{\rm{a}}^ + }\) and \({\rm{C}}{{\rm{l}}^ – }\)...
The composition of a compound is given by its formula. If the compound is an ionic compound it can have only one formula. The ionic compound magnesium chloride has the formula, MgCl2, which tells us that the compound consists of magnesium and chlorine and that there are two chlorine atoms ...
It is known that molecules or formula units are formed by the sharing of electrons (molecular bonds) or ionic charge attraction, respectively. Many compounds of chlorine are binary, where only chlorine as chloride bonds to one ion or atom....

Numerical subscripts are used if there is more than one of a particular atom. For example, we have already seen CH4, the molecular formula for methane. Naming binary (two-element) covalent compounds is similar to naming simple ionic compounds. The first element in the formula is simply list...
Atom, or group of atoms, with a negative charge due to the gain of one or more electrons. (Gain a negative --- become negative.) Two general rules for naming ionic compounds. 1. Identify and name the cation. 2. Identify and name the anion. ...
