Question

The general electronic configuration of d-block element is $(n-1)d^{1-10}n{s}^{1-2}$, where $n$ is the outer most shell. However, palladium does not follow this general electronic configuration. It has an electron configuration $[Kr{]}^{36}4d^{10}5s^0$ in order to have stability. Give a reason behind it.

Answer 1

Reason for palladium$\left(Pd\right)$ electronic configuration-

• Full d orbitals are more stable than partially filled ones,
  
• At higher energy levels, the levels are said to have degenerated which means that they have very close energies and then electrons can jump from one orbital to another very easily.
