What does the Angular Momentum Quantum Number describe? What is it's symbol? What values may it be assigned to?
|
The angular momentum quantum number describes the sublevel the electron is in within the principle energy level (symbol l). They may be designated as: s, p, d, f, or g. To each letter there is a number s=0, p=1, d=2, f=3, and g=4.
l = 0, ...(n-1) |

What does the term 'degenerate' mean?
|
equal in energy

What does the Magnetic Quantum Number describe? What is it's symbol? What values may it be assigned to?
|
The magnetic quantum number describes the number of orbitals in a given sublevel (symbol ml).
ml = -l, ...0, ... +l |
|
|
What does the Spin Quantum Number describe? What is it's symbol? What values may it be assigned to?
|
The spin quantum number describes the spin of the electron as clockwise or counter clockwise (symbol ms). It is arbitrarily assigned as either - or + 1/2
