有効核電荷（ゆうこうかくでんか、英: effective nuclear charge）とは、多電子原子系において、最外殻電子、または着目する電子が感じる中心原子核の電荷のこと。
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} ...
Example. Note that the effective nuclear charge is calculated by subtracting the screening constant from the atomic number, 26.
The shielding effect can be defined as a reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces on the ...
For electrons or electron holes in a solid, the effective mass is usually stated as a factor multiplying the rest mass of an electron, me (9.11 × 10−31 kg).
In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when pushed or pulled by an ...
Nuclear charge and effective nuclear charge. edit. Main article: Nuclear charge · Nuclear charge is defined as the number of protons in the nucleus of an ...
The classical electron radius is a combination of fundamental physical quantities that define a length scale for problems involving an electron interacting ...
But the n=2 electrons see an effective charge of Z − 1, which is the value appropriate for the charge of the nucleus, when a single electron remains in the ...
Effective atomic number, denoted by Zeff, may refer to: Effective nuclear charge of an individual atom, as felt by electrons within that atom ...
