Question

Steps to determine effective nuclear charge

Answer 1

Hey.

Here is the answer.

By using these formulas :

1.)

Z* = Z - S

where,

-> Z is the number of protons in the nucleus (Atomic Number), and

-> S is the average number of electrons between the nucleus and the electron in question (the number of non-valence electrons)

2)

Z* = (r)h / (r)z

where,

-> (r)h is the mean radius of the orbital for hydrogen, and

-> (r)z is the mean radius of the orbital for an electron configuration with nuclear charge Z.

Thanks.
