हिन्दीWhich of the following sets of quantum numbers describes an electron experiencing the highest energy in a multi-electron system according to the \( (n + l) \) rule and energy hierarchy?
Correct answer · Option 4
\( n = 4, l = 2, m_l = -2, m_s = -1/2 \)
Explanation
Calculating \( (n + l) \): Option 4 gives \( 4 + 2 = 6 \), Option 1 gives \( 4 + 1 = 5 \), Option 2 gives \( 3 + 2 = 5 \), Option 3 gives \( 3 + 1 = 4 \). The highest \( (n + l) \) value is 6.
