|
Bohr Atom
|
Niels Bohrs planetary model of the hydrogen atom.
|
|
|
Energy Level
|
the volume of space where certain electrons of specific energy are restricted to move around the nucleus. Energy levels consist of one or more orbitals.
|
|
|
Orbitals
|
the space where one or two paired electrons can be located. These are methematical functions with restricted zones, called nodes, and specific shapes
|
|
|
Outer Shell
|
The last energy level in which loosely held electons are contained. THese aer the electrons that engage in bonding and are therefore characteristic of the element.
|
|
|
Hund Rule
|
States that the most stable arrangement of electrons in teh same energy level is the one in which electrons have parallel spins (same orientation).
|
|
|
Pauli's Exclusion Principle
|
States that an orbital can hold a maximum of two electrons if they are of opposite spins.
|
|
|
Electon Configuration
|
Describes the exact arrangement of electrons (given in a superscript number) in successive shells (indicated by numbers 1,2,3...) and orbitals (s,p,d,f) of an atom, starting with the innermost orbital.
ex: 1s2, 2s2, 2p6. |
