7.6 quantum numbers

Question 1

what is the principal quantum number (n)

Answer 1

describes energy level of an atom

Question 2

what is the angular momentum quantum number (l)

Answer 2

describes the shape of the sublevel (orbital) of the atom

Question 3

what is the valu of l

Answer 3

from 1 to l-1 —- this describes what shapes are possible for each energy level

Question 4

what is the magnetic quantum number

Answer 4

describes the oribital within a sublevel

Question 5

what are the values of ml

Answer 5

between -l and l (gives the number of orbitals)

Question 6

what is the electron spin (ms)

Answer 6

electron can be going up or down, max 2 electrons per orbital, 1 going up and 1 going down.

Question 7

give number of orbitals of each orbital

Answer 7

s = 1 —– 2 electrons
p = 3 —– 6 electrons
d = 5 —– 10 electrons
f= 7 ——- 14 electrons
