Question

Compared to an electron with a principal quantum number of 1, an electron with a principal quantum number of 2 will have a

• A. lower energy
• B. higher energy
• C. negative spin
• D. positive spin

Hint:

In atomic orbitals, the energy increases with the principal quantum number. Higher quantum numbers indicate orbitals that are farther from the nucleus and therefore higher in energy.

Answer 1

The Correct Option is B

An electron with a principal quantum number of 2 will be in a higher energy state compared to an electron with a principal quantum number of 1. This is because higher quantum numbers correspond to higher energy levels in an atom.
