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…
