Question

Calculate Screening constant of Mn for 3d electron

Answer 1

Answer:

The expression for the effective nuclear charge Z

∗

is

Z

∗

=Z−S

Here, Z is the nuclear charge and S is the shielding constant.

For nickel Z=28 and S=20.45

Hence, Z

∗

=Z−S=28−20.45=7.55

Hence, the effective nuclear charge for Nickel atom is 7.55.
