Chemical Formulas

A chemical compound is any substance made of two or more elements joined together in a covalent or ionic bond. Chemical compounds contain metals and nonmetals as well as neutral and charged ions. Ionic compounds have positive and negative charges, while neutral compounds have equal amounts of positively charged and negatively charged ions. The atomic number and oxidation state of the element determines how many positively and negatively charged ions a compound will have.

When naming ionic compounds, it is customary to write the name of the more electropositive metal cation first (specifying its charge, if necessary) and then to list the name of the nonmetal anion that it forms with each oxygen atom. It is also customary to omit the prefixes and suffixes that are used to indicate how many ions of each element are present in a compound.

When writing chemical formulas, it is important to remember that the symbols for ionic compounds must be written in the correct order. This is because the overall composition of ionic compounds must be electrically neutral, and deciding how many of each ion will be needed to balance out the positive and negative charges is done by writing the chemical formulas with the metal cation first and the nonmetal anion second. The numbers of the ions are then transposed with the sign of the negative charge being dropped, and then reduced to the lowest ratio.
