quantum numbers Flashcards
n
size and energy level
l
orbital shape
ml
orbital orientation
ms
electrons direction of spin
what is the value for n
1-7 (whole numbers)
what is the value for l
n-1
what is the value for ml
-L -> +L
what is the value for ms
+ve or -ve 1/2
what shape does l=0 produce
sphere
what shape does l=1 produce
dumbell
what shape does l=2 produce
double dumbell/clover
what shape does l=3 produce
no definite shape
s orbital
0- sphere
p orbital
1- dumbell
d orbital
2- double dumbell/clover
f orbital
3- no definite shape
can there be a ZERO spin
no
pauli exclusion principle
no two electrons can have the same set of 4 quantum numbers
orbits
(3)
- 2D
- distance from nucleus is fixed
- e- path is circular
orbitals
(3)
- 3D
- distance varies
- e- has no set path
uncertainty principle
it is impossible to know the exact location and speed of an electron at a given time
complete description of an orbital consists of…
n, l, ml
complete description of an electron consists of…
n, l, ml, ms
