FC1 Electron Configuration Flashcards
1
Q
Hund’s rule
A
Electrons half full degenerate orbitals before they start pairing up because electrons repellent other electrons.
2
Q
Pauli exclusive principle
A
Maximum of 2!electrons in each orbital. They have opposite +1/2 and -1/2 spins.
3
Q
Orbital
A
A region of space around the nucleus that can hold up to 2 electrons with opposite spins.
4
Q
How to do an abbreviated electron configuration
A
Noble gas electron configuration only- THEN all other up to element.
5
Q
Auf Bau Principle
A
Full orbitals with the lowest energy first closest to the nucleus.
