The s-Block Elements


Both lithium and magnesium display several similar properties due to the diagonal relationship; however, the one which is incorrect is :

  • Both form basic carbonates

  • Both form soluble bicarbonates

  • Both form nitrides

  • Nitrates of both Li and Mg yield NO2 and O2 on heating



Both form basic carbonates

Lithium can form carbonate (Li2CO3). Lithium Carbonate is not basic in nature. On other hands, Mg can form basic carbonate.
5Mg+2 + 6CO32- + 7H2O → 4 MgCO3.Mg(OH)2.5H2O + 2HCO3-
