Group 2, alkaline Earth metals

Group 2 metals, also known as alkaline earth metals are s-block elements like Group 1, but are less reactive.

Physical properties as you go down the group are:

·         atomic radius increases,

·         s-orbital becomes further away from the nucleus,

·         metallic bond strength decreases

·         melting points decrease slightly, starting from calcium. This doesn’t apply to magnesium at the lattice arrangement of the atoms make them easier to separate.

·         Reactivity increases

·         First and second ionisation energy decreases. This is…
