To write a formula for an insoluble compound, you need to determine the charges of the ions involved and balance them to create a neutral compound. This involves using the crisscross method to determine the subscripts for each ion in the formula.
The formula for the compound of barium and fluoride is BaF2.
The formula for the binary compound of calcium and oxygen is CaO. This compound is known as calcium oxide.
The chemical formula for the ionic compound containing calcium and fluorine is CaF2.
To write the formula of a covalent compound, you need to determine the elements involved and their valencies. Use prefixes to indicate the number of atoms of each element in the compound. For example, in carbon tetrachloride (CCl4), the prefix "tetra-" indicates four chlorine atoms. The formula is then written as CCl4.
The formula for tetraphosphorus trisulfide is P4S3. This compound contains 4 phosphorus atoms and 3 sulfur atoms, thus the formula reflects the ratio of elements in the compound.

H2O A compound formed when hydrogen gas burns with oxygen.
To write the formula for an ionic compound, you first write the symbol for the cation (positively charged ion) followed by the symbol for the anion (negatively charged ion). Then, you use subscripts to indicate the ratio of ions needed to balance the charges to make it electrically neutral. The subscripts are the smallest whole numbers that will ensure the compound has a net charge of zero.
