Is there any possibility that effective nuclear charge experienced by an electron is -ve. Why/Why not?
Dear student
No, effective nuclear charge is not negative. It can be a very small number or can be zero.
The effective nuclear charge (Zeff), experienced by an electron can be expressed as:
Zeff = (Z- σ)
where Z is the actual nuclear charge (atomic number of the element) and σ (sigma) is called shielding constant.
