Answer:

effective nuclear charge =atomic no. - screaning effect

Explanation:

EC=26 -(0.35×1 +0.85×8 +2×8 +2×8) after solving we get ans

I think because I am the student of class 10 if ans is wrong please don't angry to me

The effective nuclear charge of 4s electron of Fe is, 4.1

Explanation :

As we are given that, the element is iron that has atomic number 26.

The electronic Configuration of (Fe), iron is,

1s^22s^22p^63s^23p^63d^64s^2

Formula used to calculate the effective nuclear charge is:

(Z_{eff})_{4s}=Z-\sigma

and,

σ = 0.85 × (number of electrons in (n - 1)th shell) + 1.00 × (total number of electrons in the inner shell)

= 0.85 \times 14 + 1.00 \times 10

= 21.9

So,

Z_{eff}=26-21.9=4.1

Thus, the effective nuclear charge of 4s electron of Fe is, 4.1
