Quantum Numbers

Question 1

What is the principle quantum number (n) ? – role, value

Answer 1

role - N tells you energy level (which shell the electron is in)
Value - positive integer values (n=1,2,3…)

Question 2

What is the angular momentum number? (l) – role, value,

Answer 2

role - determines shape of the orbital
(l=0 - s orbital, l=1 - p orbital, 1=2 - d orbital, l=3 - f orbital

Values = integer vales from 0 - (n-1)

Question 3

What is the magnetic quantum number? (ml) – role, value,

Answer 3

role - determines orientational of orbital in space

Values - for each value of (l) there is a -(l),0, (l)

Question 4

What is a spin number (ms)? - role and value

Answer 4

role - determines spin of electron, up or down
