Question

An atom gets most energetic when:

• A. The Electron is removed from L shell
• B. The Electron is removed from the highest shell
  
• C. The Electron is not at all removed
• D. The Electron is removed from K shell

Answer 1

The correct option is D

The Electron is removed from K shell

Its toughest to remove an electron closest to the nucleus which is a K-shell electron. Maximum amount of energy is needed to be supplied to remove an electron from K-shell as compared to other shells. Hence, the atom gets the most excited when an electron from K-Shell is removed.
