Effective nuclear charge: Measurement, Calculations & Description

In atomic physics, the effective nuclear charge of an electron in a multi-electron atom or ion is the number of elementary charges ( e {\displaystyle e} ) an electron experiences by the nucleus. It is denoted by Zeff or Z*. The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from…
