Chemistry: Cambridge International GCSE Supplement, topic 2.5.1
Covalent Bonding
Covalent bonds are formed when 2 non-metal atoms share pairs of electrons. Covalent bonds are strong because the shared electrons are attracted to the nucleus of both atoms. Covalently bonded substances can be:
Small molecules
- E.g. water.
