The general valence shell electronic configuration of `p`-block elements is

Options

A. `ms^(2)np^(0-6)`
B. `ns^(2)np^(1-6)`
C. `ns^(0-2)np^(1-6)`
D. `ns^(1-2)np^(1-6)`

Answer

B

Explanation

In `p`-block elements, the `ns` orbitals (i.e., `s` orbitaks of outermost shell) are already completely filled but their `np` orbitals get progressively filled by the addition of one electron at a time as we move from group `13` to `18`.
