Question

What is the maximum number of electron in an atom that can have the following quantum numbers? (a) n = 3, ml = -2; (b) n = 4, l = 3; (c) n = 5, l = 3, ml = 2; (d) n = 4, l = 1, ml = 0.

Answer #1

(a) n = 3, ml = -2;

if mL = -2; then, we can choose from:

l = n-1 = 3-1 = 2

so this is the max mL value and only one we can have

so

+/- 1/2 spins, total of 2 electrons

(b) n = 4, l = 3;

we could have:

ml = 0, +/-1, +/-2, +/-3,

each will have +/- spins, so

totla ml = 1,2,2,2 = 7

times two spins

7*2 = 14 electrons

(c) n = 5, l = 3, ml = 2;

for ml = 2, we could only have +/- 1/2 spins --> 2 electrons

so total of 2 electrons

(d) n = 4, l = 1, ml = 0.

once again, we could only have +/- 1/2 spins --> 2 electrons

What is the maximum number of electrons in an atom that can have
these quantum numbers: (Remember the shortcut: n2 = #
______________________ whereas 2n2 = # ________________ where n
stands for _________________________________).
n=4 n=5, ml = +1 n=5, ms = + Â½ n=3, l = 2 n=2, l = 1

Quantum numbers arise naturally from the mathematics used to
describe the possible states of an electron in an atom. The four
quantum numbers, the principal quantum number (n), the angular
momentum quantum number (â„“), the magnetic quantum number (mâ„“), and
the spin quantum number (ms) have strict rules which govern the
possible values. Identify allowable combinations of quantum numbers
for an electron. Select all that apply.
a) n=4, l=2, ml=3, ms=+1/2
b) n=6, l=6, ml= 1, ms=-1/2
c) n=3, l=1,...

Each electron in an atom may be described by a set of four quantum
