The bonds in salt compounds are called ionic because they both have an electrical charge—the chloride ion is negatively charged and the sodium ion is positively charged.
Ionization is a formation of ions from neutral atoms or molecules.
SO₂ + H₂O = HSO₃⁻ + H⁺
Mg(OH)₂ = Mg²⁺ + 2OH⁻
The lanthanides and actinides are separated from the rest of the periodic table, usually appearing as separate rows at the bottom. The reason for this placement has to do with the electron configurations of these elements.
