Question

effective nuclear charge for 3d of nickel​

Answer 1

Answer:

7.55

Explanation:

z* = z - s

or, z* = 28 - 20.45 = 7.55

Answer 2

The expression for the effective nuclear charge

Z∗Z∗ iis

z∗=Z−Z∗=Z−S

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

For nickel

Z=28

Z=28 and

S=20.45

S=20.45

Hence,

Z∗=Z−S=28−20.4 =7.55

Z∗=Z−S=28−20.45=7.55

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