Question

Calculate the effective nuclear charge of 3p electron of aluminum

Answer 1

Answer:

The effective nuclear charge (often symbolized as Zₑff or Z*) is the net positive charge experienced by an electron in a polyelectronic atom. The term "effective" is used because the shielding effect of negatively charged electrons prevents higher orbital electrons form experiencing the full nuclear charge of the nucleus due to the repelling effect of inner-layer electrons. The effective nuclear charge experienced by the electron is also called the core charge.
