The term nuclear charge refers to the precise charge of the nucleus, which, in units of fundamental charge, is equal to the number of protons, Z. The term effective nuclear charge is used to mean the apparent charge that determines the radius of the outermost electron(s) in an atom. Which quantity below can be used to approximate the effective nuclear charge by accounting for shielding by the inner electrons?

Select the correct answer below:

2Z

Z+ the number of shielding electrons

Z− the number of shielding electrons

the number of shielding electrons

The quantity that can be used to approximate the effective nuclear charge, making sure that the inner electrons is being accounted for is The number of shielding Electron.

Explanation:

Effective nuclear charge is estimated from slaters rules. It is the nuclear charge an electron actually experiences in its orbit and it depends on the number of screening electrons. Slaters rule is a set steps that obtains the effective clear charge using a screening or shielding constant which depends on the orbital of the screening electrons.
