{7} Electron Configuration and Spin Flashcards
1
Q
Define:
Electron Configuration?
A
The particular orbitals that electrons occupy for that atom.
2
Q
Define:
Pauli exclusion principle?
A
No two electrons in an atom can have the same 4 quantum numbers
3
Q
Define:
Hund’s rule?
A
When filling degenerate orbitals, orbitals of the same energy, electrons fill them singly first wih parallel spins
4
Q
Define:
Aufbau principle?
A
The pattern of filling orbitals to create an electron configuration
(Starting 1ith 1s -> 2s -> 2p -> 3s etc.)
5
Q
Define:
Valence electrons?
A
Electrons on the outermost sublevel (or orbital)
6
Q
Define:
Core electrons?
A
Core electrons are the electrons that are not valence electrons (inside)
