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.

An example is the carbon monosulfide, CS.
CaF2
Well for sodium chloride, it would be NaCl
chemical formula is an abbreviation representing the molecules of an element or a compound . The number and kind of the atoms of elements can be understood from the chemical formula . The symbol and number of atoms of each element will be indicated in the chemical formula.

You use the prefix of the words to write the formula for a covalent compound, example "di-" is the prefix and it is 2.
An example is the carbon monosulfide, CS.
CaF2

H2O A compound formed when hydrogen gas burns with oxygen.
With a molecular formula we can calculate the molar mass and the chemical composition of a compound, also we can write chemical equations.
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.
