Inorganic Chemistry: Group II

Question	Answer
Inorganic Chemistry: Group II	Group II elements are all reactive metals. They are good reducing agents.
Reducing Power	Down the group, the atomic radius of Group II elements increases and as a result, ionisation energy decreases, i.e. increasing ease of losing electrons by the metal.. The tendency of the metal to be oxidised increases.

Thermal Decomposition of the Nitrates, Carbonates and Hydroxides	Down the group, the radius of the metal cation, M2+, increases and its charge density decreases. As a result, the ability of M2+ to polarise the large NO3- anion decreases and the N-O bonds are weakened to a smaller extent. Thermal stability of the nitrates of Group !! elements increases down the group.
