Among the pairs of orbital which orbital will experience more effective nuclear charge ?
3d and 3p

Text Solution

Verified by Experts

Greater the penetration of the electron present towards the nucleus more is the magnitude of the effective nuclear charge. So depending upon this factor,
Out of 2s and 3s, 2s will experience more effective nuclear charge.
