Nitride, any of a class of chemical compounds in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals. It is used as a corrosion inhibitor in mortar. Lithium nitrate also works in a similar way but decomposes slightly differently due to the higher charge density on the lithium ion: 4LiNO All Rights Reserved. 4LiNO3(s) → 2Li2O(s) + 4NO2(g) + … Equation for the thermal decomposition of lithium nitrate: 4LiNO3 -> 2Li2O + 4NO2 + O2 Lithium dioxide decomposes differently to the other G1 nitrates because lithium's high charge density... polarises the O-N bond enough to break it For example, a typical Group 2 nitrate like magnesium nitrate decomposes like this: In Group 1, lithium nitrate behaves in the same way - producing lithium oxide, nitrogen dioxide and oxygen. Nitrides contain the nitride ion (N3−), and, similar to carbides, nitrides can be classified into three general categories: the previous answer is not correct....lithium ion is very small...so the lattice energy of lithium nitrate becomes very high....increase of lattice energy leads to the stability of a crystal or any solids....so the lithium nitrate doesnot decompose.....same to lithium carbonate.. It behaves like group 2 elements.
