Answer :
The estimated effective nuclear charge, Zeff, experienced by an electron in a 3p orbital of a chlorine atom is 6.1.
The effective nuclear charge is the charge experienced by the outermost valence electrons of an atom. the effective nuclear charge is given as :
Zeff = Z - s
where,
Z is the actual nuclear charge
s is the screening costant
The electronic configuration for the chlorine atom is :
₁₇Cl = (1s²) (2s² 2p⁶) (3s² 3p⁵)
The formula for calculating screening constant of 3p electron is :
s = ( 0.35 ( number of electrons in n ) + 0.85 ( electron in (n-1 ) ) + 1 ( electrons in ( n-2 )
s = 0.35 (6) + 0.85 ( 8 ) + 1 ( 2 )
s = 10.9
Zeff = Z - s
Zeff = 17 - 10.9
Zeff = 6.1
Thus, The estimated effective nuclear charge, Zeff, experienced by an electron in a 3p orbital of a chlorine atom is 6.1.
