Answer 1

ANSWER

When an extra electron is added in nitrogen atom, added electron will be screened by five electrons in second orbit (2s 2 2p 3) and two electrons in first orbit (1s 2).

Now screening constant, σ=5×0.35 in nth orbit+2×0.85 in (n−1)th orbit

=1.75+1.70=3.45

∴ Effective nuclear charge =7−3.45=3.55.
