Electron Configurations
Cards in this deck (15)
- 1Valence Electrons (ve-)are electrons in the atom's highest outermost orbital.
- 2Principle Quantum Number/Principle Energy Levels (n)indicates the relative size and energies of atomic orbitals.
As the n increase, the orbital becomes larger
Are the major energy levels of an atom
"Floor Level" - 3Energy Sublevels / Subshellare the energy levels contained within principle energy level. "Room Type"
- 4Atomic Orbitalis a three-dimensional region around the nucleus of an atom that describes the electron's probable location. "Bunk Bed"
- 5—
- 6Atom's Electron ConfigurationThe arrangement of electrons in an atom " Manager Code"
- 7Aufbau Principlestates that each electron occupies the lowest energy orbital available. "Lazy Electrons"
All orbitals related to an energy sublevel are of equal energy.
The energy sublevels within a principle energy level have different energies such as 2p is higher in energy than 2s.
The sequence of energy sublevels within an energy level is s, p, d, f.
Orbitals related to energy sublevels within one energy level can overlap orbitals related to energy sublevels within another principal energy level. - 8—
- 9Hund's Rulestates that single electrons with the same spin must occupy each equal energy orbital before additional electrons wth oppostite spins can occupy the same orbital.
"Each wants a bunk bed for themselves before doubling up".
- 10—
- 11Pauli Exculusion Principalstates that a maximum of two electrons may occpy a single atomic orbital but only if the electrons have oppostite spins.
Clockwise and counterclockwise
"Pauli wants 2 crackers"
"Bunk Beds each hold 2 with pillows on opposite ends". - 12—
- 13Electron Configurations Notation "Manger Code"
- 14Noble Gas Notation "short hand"
- 15Stable Electron ConfigurationOrder of stability from most to least stable.
Full enrgy levels (floor).
Full subleves (room).
Half full sublevels (room).
