7.6 quantum numbers Flashcards
1
Q
what is the principal quantum number (n)
A
describes energy level of an atom
2
Q
what is the angular momentum quantum number (l)
A
describes the shape of the sublevel (orbital) of the atom
3
Q
what is the valu of l
A
from 1 to l-1 —- this describes what shapes are possible for each energy level
4
Q
what is the magnetic quantum number
A
describes the oribital within a sublevel
5
Q
what are the values of ml
A
between -l and l (gives the number of orbitals)
6
Q
what is the electron spin (ms)
A
electron can be going up or down, max 2 electrons per orbital, 1 going up and 1 going down.
7
Q
give number of orbitals of each orbital
A
s = 1 —– 2 electrons
p = 3 —– 6 electrons
d = 5 —– 10 electrons
f= 7 ——- 14 electrons
