Both lithium and magnesium display several similar properties due to the diagonal relationship; however, the one which is incorrect is :
1 Both form basic carbonates
2 Both form soluble bicarbonates
3 Both form nitrides
4 Nitrates of both Li and Mg yield \({\rm{N}}{{\rm{O}}_{\rm{2}}}\,\,{\rm{and}}\,\,{{\rm{O}}_{\rm{2}}}\) on heating
Explanation:
Mg can form basic carbonate like \({\rm{3MgC}}{{\rm{O}}_{\rm{3}}}{\rm{.Mg}}{\left( {{\rm{OH}}} \right)_{\rm{2}}}{\rm{.3}}{{\rm{H}}_{\rm{2}}}{\rm{O}} \downarrow \) While Li can form only carbonate \(\left( {{\rm{L}}{{\rm{i}}_{\rm{2}}}{\rm{C}}{{\rm{O}}_{\rm{3}}}} \right)\) not basic carbonate.

Lithium shows diagonal relationship with
1 \(\mathrm{Mg}\)
2 \(\mathrm{Al}\)
3 \(\mathrm{Be}\)
4 \(\mathrm{Na}\)
Explanation:
\(\mathrm{Li}-\mathrm{Mg}, \mathrm{Be}-\mathrm{Al}\) and \(\mathrm{B}-\mathrm{Si}\) show diagonal relationship. It is due to similar radii, similar electronegativity and similar polarising power.

\(\mathrm{Mg}\) and \(\mathrm{Li}\) are similar in their properties due to
1 same e/m ratio
2 same electron affinity
3 same group
4 same ionisation potential
Explanation:
\(\mathrm{Mg}\) and \(\mathrm{Li}\) are similar in their properties due to the similar electronegativity and polarising power, i.e. they have same charge/radius (e/m) ratio.
