IB Chemistry HL 2.1.2 Ionic bonding
Define ionic bonding precisely and construct correct formulas for ionic compounds by balancing charges on metal ions and polyatomic ions.
How this is tested
- state ionic bonding as electrostatic attraction between oppositely charged ions
- balance ion charges to write formulae, e.g. Ni(NO3)2 and Al2(SO4)3
- distinguish ionic bonding from covalent bonding: electron transfer vs shared pairs
