Answer -
Similaritiesbetween lithium and magnesium are as follows.
(i)┬аBoth Li and Mg reactslowly with cold water.
(ii)┬аThe oxides of bothLi and Mg are much less soluble in water and their hydroxides decompose at hightemperature.
(iii)┬аBoth Li and Mg react withN2┬аto form nitrides.
(iv)┬аNeither Li nor Mg formperoxides or superoxides.
(v)┬аThe carbonates of both arecovalent in nature. Also, these decompose on heating.
(vi)┬аLi and Mg do not formsolid bicarbonates.
(vii)┬аBoth LiCl and MgCl2┬аare soluble inethanol owing to their covalent nature.
(viii)┬аBoth LiCl and MgCl2┬аare deliquescent in nature. Theycrystallize from aqueous solutions as hydrates, for example,┬а
and
