Atomic Structure & PeriodicityShielding Effect
The reduction in the nuclear attraction felt by an outer electron caused by repulsion from electrons in inner shells.
Atomic Structure & PeriodicitySpin Quantum Number
The quantum number mₛ describing the intrinsic angular momentum of an electron, restricted to +½ or −½.
