NEET Chemistry QUESTION #7352
Question 1
The maximum number of electrons in a subshell of an atom is determined by which formula?
  • \(2n^2\)
  • \(4\ell + 2\)✔️
  • \(2\ell + 1\)
  • \(4\ell - 2\)
Correct Answer Explanation
Key formulae:
  • Max electrons in a shell: \(2n^2\)
  • Max electrons in a subshell: \(4\ell + 2\)
  • Number of orbitals in a subshell: \(2\ell + 1\)
For example, d-subshell (\(\ell = 2\)): \(4(2)+2 = 10\) electrons. f-subshell (\(\ell = 3\)): \(4(3)+2 = 14\) electrons.
