Question

Explain why Mg experiences a greater Z_eff than does P.

Answer 1

Answer #1

Mg has Electronic configuration = [Ne] 3s2 &

P has Electronic configuration = [Ne] 3s2 3p3

Shielding Effect :- Ability of Nucleus to hold the Electrons towards itself is known as shielding Effect or screening Effect.

Shielding Effect order : s > p > d > f

Hence inner orbital s has more shielding Effect as compare to outer f orbital.

Effective Nuclear Charge (Zeff) :- This is the Net positive charge experienced by the electron from the nucleus.

Effective Nuclear charge of Mg is greater than P because In Mg(magnesium) 3s2 has greater shielding Effect as compare to 3p3 in P(phosphorus).
