Question

Effective nuclear charge on 3d electron of zn

Answer 1

Hii friend,

Here is your answer....

E.c of Zinc is { 1s² 2s² 2p6 3s² 3p6 4s² 3d10}

As for 4s electron the value will be 0.

For (n) shell => 9 ×0.35 = 3.15

For (n-1) shell => 8×0.85 = 6.8

For other inner shells => 10×1 =10

Total (S) = 19.95

Z* = Z -S

z* = 30 -19.95

Z * = 10.05.
