Which element from following is NOT considered as transition element on the basis of electronic configuration?

Which element from following is NOT considered as transition element on the basis of electronic configuration?
  1. Ti
  2. V
  3. Hg
  4. Ag

Solution

Transition elements have partially filled d-orbitals. $\mathrm{Hg}=[\mathrm{Xe}] 5 \mathrm{~d}^{10} 6 \mathrm{~s}^2$
Among the given elements, Hg has completely filled d-orbital in its ground state. Hence, it is not considered as transition element.
Thinking Hatke - Q. 29 $\mathrm{Zn}, \mathrm{Cd}, \mathrm{Hg}$ belongs to the same group having completely filled d-electrons.
