Why atoms share electrons
Why atoms share electrons
Covalent bonding usually happens between non-metal atoms. Instead of transferring electrons, the atoms share electrons so each can reach a full outer shell.
Step-by-step lessons on CIE IGCSE Chemistry Simple molecules and covalent bonds. Each one builds up to exam-style questions. Build a solid grasp of atomic structure, bonding and the mole concept early, since these underpin almost every other topic, then move on to the more calculation-heavy quantitative and organic chemistry content.
