Solution:

Likenesses among lithium and magnesium:

(I) lithium and magnesium respond delayed with cold water.

(ii) oxides of lithium and magnesium are less dissolvable in H2O. additionally the hydroxides of both break down at high

(iii) Nitrides is framed from both the lithium and magnesium when they respond with N2.

(iv) Neither Li nor Mg structure superoxides or peroxides.

(v) Both the carbonates of lithium and magnesium are normally covalent. They decays on warming.

(vi) They don’t frame bicarbonates which are strong.

(vii) Both MgCl2 and LiCl are dissolvable in ethanol since they are normally covalent.

(viii) Both MgCl2 and LiCl are normally deliquescent. They solidify as hydrates from watery arrangements.
