Multi-electron atom

[Doreen Liu 4D]

What are some of the factors affecting the energy of an electron in a many-electron atom?

[105335337]

Some factors impacting the energy of electron in a multi-electron atom are:

Electron-Electron repulsion
Shielding
Penetration
Zeff

Multi-electron atoms must follow the Aufbau principle, which states that electrons fill the lowest-energy orbitals before the largest. So s<p<d<f within the same energy level. For us, be able to write and interpret quantum numbers (n, l, ml, ms) and electron configurations.
