Question

Electrons having maximum number of low shielding electrons:

• A. $\left[Xe\right]4f^{14},5d^{10},6s^2,6p^2$
• B. $\left[Rn\right]4{5f}^{14},6d^1,7s^2$
• C. $\left[Ar\right]3d^{10},4s^2$
• D. $\left[Ne\right]3s^2,3p^1$

Answer 1

The correct option is A $\left[Xe\right]4f^{14},5d^{10},6s^2,6p^2$

d block and f block electrons are known as low shielding electron

so

$\left[Xe\right]4f^{14},5d^{10},6s^2,6p^2$ has maximum number of d and f block element.
