WebGenerally the melting point of the alkali metals decreases down the group. This is because as the ions get larger the distance between the bonding electrons and the positive nucleus gets larger and reduces the overall attraction between the two. For similar reasons the electronegativity decreases. WebAs the alkali metals have very low ionization energies, the energy from the flame of a bunsen burner is sufficient to excite the electrons of alkali metals to higher energy levels. The excited state being unstable, these electrons return to their original energy levels, emitting extra energy, which gives characteristic flame colorations.
