Octet Rule: Atoms try to get 8 electrons in outermost shell
3 Reasons for bonding: Lower energy, Stability, Noble gas config
Modern Periodic Law: Properties are periodic functions of atomic numbers - Moseley
Structure: 7 periods (horizontal), 18 groups (vertical), s-block 1-2, p-block 13-18, d-block 3-12, f-block
