Reactions of Group 2 (AQA A-Level Chemistry): Flashcards

Alkaline earth metals

Metal hydroxide and hydrogen gas

From 0 to +2

Increases down the group

Very slowly

$MgO$ (magnesium oxide) and $H_2$

Barium ($Ba$)

Increased shielding, weaker nuclear attraction, easier e⁻ loss

Reducing agent to reduce $TiCl_4$ to $Ti$

$M^{2+}$ (divalent/2+)
