Question

Why berillium and magnesium do not impart characterstick colour to flame?

Answer 1

The energy gap between level gets smaller as the n value for the level increases (i.e., it takes less energy to jump from 4 to 5 than from 2 to 3). When beryllium and magnesium atoms are excited and then the electrons jump down to the ground state, these transitions have higher energy (because their outer electrons are in lower levels), and the light emitted is in the ultraviolet, so we cannot see it. Thus, no color.
