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.
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.
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.
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.

Scientist combine the symbols for different elements when they write chemical formulas.
With a molecular formula we can calculate the molar mass and the chemical composition of a compound, also we can write chemical equations.
To write the chemical formula of an ionic compound, you balance the charges of the ions to achieve neutrality. This involves using subscripts to ensure that the positive and negative charges cancel out. The formula is typically written using the smallest whole number ratio of ions.
To write chemical formulas with oxidation numbers, first determine the oxidation number of each element in the compound based on their typical values. Then, use these oxidation numbers to balance the charges of cations and anions in the compound. Finally, write the chemical formula using subscripts to ensure that the overall charge of the compound is neutral.
