Arrangment of electrons Flashcards
1
Q
Aufbau principle
A
when building up the electron configuration of an element in its ground state, the electrons occupy the lowest available energy level
2
Q
Hunds rule of maximum multiplicity
A
when two or more energy orbitals of equal energy are available electrons fill them singularly before filling them in pairs
3
Q
Pauli exclusion principle
A
no more than two electrons can occupy an orbital, and they must have opposite spin
