Answer:
Effective nuclear charge Z
eff
=Z−S
where Z = atomic number
and S = screening constant
= 0.35 per electron for electron in nth orbit.
= 0.85 per electron for electrons in (n - 1)th orbit
= 1.00 per electron for electrons in (n - 2)th, (n - 3)th, (n - 4)th orbit
= 0.30 per electron in 1s-orbital (when alone)
This electron is screened by 18 electrons in (n - 1), 8-electrons in (n - 2) and 2-electrons in (n-3)
Thus, σ=
8×0.85
