The metal which does not form ammonium nitrate by reaction with dilute nitric acid is
Al
Fe
Pb
Mg
Lead form nitric oxide with dil. HNO3
3Pb+8HNO3→3Pb(NO3)2+2NO+4H2O
Therefore, total number of lone pair of electron on central atom Xenon = 1
A nitrate which does not produce nitrogen dioxide on heating.
A nitrate which does not leave black residue on heating
Dilute nitric acid is considered as a typical acid but not so in its reaction with metals
A metallic nitate that decripitates on heating
