Write the number of each atom in the chemical formulas for all of the possible combinations of positive and negative ions found
adell [148]

A chemical formula is obtained from the number of atoms in a compound.

Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
