Miscellanous out of order unit 1 & 2 theory crds Flashcards
Electron Configuration
A shorthand method of writing the location of electrons by sublevels.
Photon
Energy given off in the form of light by an excited electron. Otherwise known as a “quanta of light”.
Sublevel
Principal energy levels are broken down into sublevels designated s, p, d, or f upon which electrons travel.
Orbital
Sublevels can be broken down into regions called “orbitals”. An orbital is defined as the most probable location for finding an electron. Each orbital holds 2 electrons.
Orbital Diagram
Shorthand method of writing the location of electrons by orbital.
Pauli Exclusion Principle
If there are two electrons in an orbital, they must have opposite (paired) spins.
Hund’s Rule
When filling sublevels other than s, electrons are placed in individual orbitals before they are paired up.
Electrons fill like people do on a bus. You would never sit right next to someone you do not know if there are free seats available, unless of course all the seats are taken then you must pair up.
So, when working with the p sublevel, electrons fill like this…up, up, up….down, down, down…
Quantum of Energy
Absorbed when an electron moves from its ground state to its excited state.
