Question

The effective nuclear charge decrease with increase in _____qunatum number
A) principal
B) azimuthal
C) magnetic
D) spin​

Answer 1

Answer:

The answer is azimuthal quantum number.

Answer 2

Answer is Option (B)

Explanation:

We know that,

• For a given shell (principal quantum number), the $Z_{eff}$ experienced by the electron decreases with increase of Azimuthal Quantum Number (l), that is,
• The s orbital electron will be more tightly bound to the nucleus than p orbital electron which in turn will be better tightly bound than the d orbital electron.
• The energy of electrons in s orbital will be lower (more negative) than that of p orbital electron which will have less energy than that of d orbital electron and so on.
