Question

Write a set of quantum numbers for each of the electrons with an n of 4 in a Se atom.

a. n=4,l=0,ml=0,ms=+1/2
b. n=4,l=1,ml=0,ms=−1/2
c. n=4,l=2,ml=1,ms=+1/2
d. n=4,l=3,ml=0,ms=−1/2

Answer 1

The quantum numbers for the electron in the n=4 shell of a Se atom are n=4,l=0,ml=0,ms=+1/2; n=4,l=1,ml=0,ms=−1/2; n=4,l=2,ml=1,ms=+1/2; n=4,l=3,ml=0,ms=−1/2.

Step-by-step explanation:

The quantum numbers for the electron in the n=4 shell of a Se atom are:

a. n=4, l=0, ml=0, ms=+1/2

b. n=4, l=1, ml=0, ms=−1/2

c. n=4, l=2, ml=1, ms=+1/2

d. n=4, l=3, ml=0, ms=−1/2

Each set of quantum numbers represents a different electron with a different orbital and spin state within the n=4 shell.

These quantum numbers describe the energy level (n), angular momentum (l), magnetic quantum number (ml), and spin quantum number (ms) of each electron.
