What is the total number of orbitals available and maximum electrons accommodated in the \( n = 5 \) shell?

  1. 9 orbitals and 18 electrons
  2. 25 orbitals and 50 electrons
  3. 16 orbitals and 32 electrons
  4. 5 orbitals and 10 electrons

Correct answer · Option 2

25 orbitals and 50 electrons

Explanation

For principal shell \( n \), total orbitals = \( n^2 \) (\( 5^2 = 25 \)) and maximum electrons = \( 2n^2 \) (\( 2(25) = 50 \)).
