thermal decomposition of group 1 nitrates

As you go down the Group, the carbonates have to be heated more strongly before they will decompose. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. Group 2 metals (like magnesium) give NO2 and O2 as well as the metal oxide: 2 Mg(NO3)2 (s) --> 2 MgO (s) + 4 NO2 (g) + O2 (g) Group 1 metals are different. The thermal decomposition of cobalt, nickel, manganese, zinc, and copper nitrates supported on nanometric alumina was investigated and compared with decomposition of corresponding bulk nitrates.
