Electrovalent (ionic) bonding: electron dot structures of NaCl, MgCl2 and CaO
Properties of electrovalent compounds: state, melting and boiling points, conductivity and dissociation in solution or melt
Covalent bonding: duplet and octet; non-polar molecules H2, Cl2, O2, N2, CCl4 and CH4
Polar covalent molecules HCl, NH3 and H2O: electronegativity difference and structures
Properties of covalent compounds; comparison of electrovalent and covalent compounds
Coordinate bonding: lone pair; formation of hydronium (H3O+) and ammonium (NH4+) ions
