• A carbon atom has an electron arrangement of 2.4.
It has 4 valance electrons.
• Each carbon atom needs 4 more electrons to
achieve a stable octet electron arrangement.
• A chloride ion has an electron arrangement 2.8.7. It
has 7 valance electrons.
• Each chloride ion needs 1 more electron to achieve
a stable octet electron arrangement.
• 4 chloride ions will combine with 1 carbon atom
through the sharing of electrons. Each of 4 chloride
ions contributes 1 electron and 1 carbon atom
contributes 4 electrons for sharing.

7. • One carbon atom is bonded to each of 4 chlorine
atoms by a shared pair of electrons so that all the
five atoms achieve stable octet electron
arrangement.
• Hence, a covalent molecule, CCl4, with 4 single
covalent bonds is formed.
