QUESTION:
Why are Group 1B elements more stable than Group 1A elements even though they seem to have the same outer electron configuration, \(ns^1\) where n is the principal quantum number of the outermost shell?
ANSWER:Step 1 of 2
1A and 1B both groups have similar electronic configuration. Only one electron in their outermost shells .The chemical properties of these both groups are quite different.
The first ionization of group 1B elements are very high when compare to the group 1A elements.
The higher ionization energies of the Group 1B elements result from incomplete shielding
of the nucleus by the inner d electrons .
