|
|
Heisenburg
|
uncertainty principle
|
|
|
uncertainty principle
|
states that it is impossible to determine simaltaneously bothe the position and velocity of an electron or any other particle
|
|
|
quantum theory
|
described the location of electrons in terms of orbitals
|
|
|
orbital
|
a three dimensional region about the nucleus in which a particular electron can be located
|
|
|
principal quantum number

hund's rule
|
orbitals of equal energy are each occupied y one electron before any one orbital is occupied by a second electron and all electrons in asingl occupied orbitals must have the same spin
