Highest energy will be absorbed to eject out the electron in the configuration.

Options

  1. A1 s^2 2 s^2 2 p^1
  2. B1 s^2 2 s^2 2 p^3
  3. C1 s^2 2 s^2 2 p^2
  4. D1 s^2 2 s^2 2 p^4

Correct answer

B. 1 s^2 2 s^2 2 p^3

Step-by-step solution

The electron will move from a lower stationary state to a higher stationary state when required amount of energy is absorbed by the electron or energy is emitted when electron moves from higher stationary state to lower stationary state. The energy does not take place in a continuous manner.
