What are the four quantum numbers n l ml and ms that correctly describes one of the valence electrons in a ground-state magnesium atom?

Answer 1

A 4d electron

Answer 2

n = 3 l = 2 m(l) = -2 m(s) = -1/2

there are obviously more numbers than that,

but the first electron would have have the above quantum number

n = energy level

l = orbital (0 is s, 1 is p, 2 is d, 3 is f)(can technically go up to the n value)

m(l) = -l,....,l

m(s) = spin where it equals -1/2 and 1/2 for every m(l)

hope this helps!

Answer 3

Two valence electrons in Mg
