For each value of the principal quantum number n, what are the possible values of the electron spin quantum number m_s? a. 0
b. -3/2
c. +3/2
d. +1/2
e. -1/2

d) and e)

Explanation:

For any value of the principal quantum n, the only possible values of the electron  spin quantum number m_s are + 1/2 and -1/2.Since this number is related with the angular momentum of the electron, it has a magnitude (1/2) and an orientation given by the sign (+ or -)So, the only right answers are d) and e).

Magma  is composed of molten rock and is  stored  in the earth's crust. lava is  magma  that reaches the surface of our planet through a volcano vent.
