The stability of the two compounds
of metals also follow a pattern that we would expect.
The nitrates and hydroxides of the
most reactive metals are either stable to heat or if they do
decompose, then do not decompose to the same extent as those of
the rest of the metals in the series.
The hydroxides of all
group 1 metals are stable to heat.
The nitrates of group 1 metals
decompose to the nitrite and oxygen.
