Question

Ionization energy depends upon :

• A. principal quantum number
• B. azimuthal quantum number
• C. magnetic quantum number
• D. spin quantum number

Answer 1

Answer: (A), (B)

The correct options are
A azimuthal quantum number
B principal quantum number

"The amount of energy required to remove the most loosely bound electron or the outermost electron from an isolated gaseous atom of an element in its lowest energy state or the ground state to produce a cation is known as ionization potential or ionization energy of that element."

Factors Affecting Ionization Potential
1. Charge in the nucleus

2. Atomic radius

3. Completely and partially filled in shells, these three factors are related to principle and azimuthal quantum numbers but not with magnetic and spin quantum numbers.
principle quantum number tells us about the shells and azimuthal quantum numbers tell us about the orbitals
Hence, options A, B are correct.
