An example is the carbon monosulfide, CS.
To write the formula for a covalent compound, you would use the prefixes that indicate the number of atoms of each element present in the molecule. For example, nitrogen dioxide is written as NO2, where "mono" is not used for the first element. An example of a covalent compound is methane (CH4), where one carbon atom is bonded to four hydrogen atoms through covalent bonds.
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.
To write the chemical formula for the covalent compound formed by chlorine atoms (Cl), you would write "Cl₂" since chlorine forms a diatomic molecule. The formula Cl₂ indicates that two chlorine atoms are covalently bonded together.
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.
The formula for the compound of barium and fluoride is BaF2.

To write the formula of a covalent compound like silicon dioxide, determine the number of each element's valence electrons from the periodic table (Si has 4, O has 6). Then, balance the number of valence electrons between the atoms by sharing electrons to form a stable octet (or duet for hydrogen and helium). In the case of silicon dioxide, two oxygen atoms share electrons with one silicon atom to form SiO2.

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.
The formula for the compound of barium and fluoride is BaF2.
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 binary compound of calcium and oxygen is CaO. This compound is known as calcium oxide.
It is written as Na2CO3. It is a base compound.
The chemical formula for the ionic compound containing calcium and fluorine is CaF2.
