Identify the number of valence electrons for a neutral carbon atom, which is 4.
Count the number of non-bonding electrons around the carbon atom in the Lewis structure of CO. In this structure, carbon has 1 lone pair, which means 2 non-bonding electrons.
Count the number of bonds carbon forms in the CO molecule. Carbon forms a triple bond with oxygen, contributing 3 bonding pairs or 6 electrons.
Use the formal charge formula: Formal Charge = (Valence Electrons) - (Non-bonding Electrons) - (Bonding Electrons/2). Substitute the values: Formal Charge = 4 - 2 - (6/2).
Simplify the expression to find the formal charge of the carbon atom in CO.
