An example is the carbon monosulfide, CS.

By listing the nonmetals in order, generally from left to right on the periodic table, and indicating subscripts as appropriate. For instance, a classic example of a covalently bonded chemical is carbon dioxide, which is written CO2.
Formula: AgI
CaO.

You use the prefix of the words to write the formula for a covalent compound, example "di-" is the prefix and it is 2.

What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
The molecular formula for iodine pentafluoride is IF5. No prefix in front of iodine is understood to be one, but mono- is not used for the first element in a binary covalent compount. The prefix penta- means five, so the subscript for fluoride is 5. Unfortunately, there is no way to write the 5 as a subscript.
Formula: AgI
Formula: Li2O
CaO.
Formula: BCl3
Pb3(PO4)2
It is written as Na2CO3. It is a base compound.
