The compound CCl doesn't exist. This is because carbon (C) typically forms four bonds, and chlorine (Cl) typically forms one bond.

To have a stable compound, you would need more chlorine atoms to satisfy the bonding requirements of the carbon atom. The most likely compound you're referring to is CCl₄, which is carbon tetrachloride.

In CCl₄, there are a total of 5 atoms:

* 1 carbon atom (C)
