Question

In an atom, what is the maximum number of electrons that can have the following quantum numbers?

(a) n = 3, ms = +1/2

(b) n = 6, l = 2

(c) n = 3, l = 2, ml = -1

(d) n = 4, l = 3, ml = +1

Answer #1

n = 3, ms = +1/2

the rule

# electrons = 2n^2

then

for

n = 3; ... 2*(3)^2 = 18 electrons, but is Ms = +1/2; only one half is possible, then 9 electrons

b)

for n = 6

n = 2*(6^2) = 72 electrons

for l = 2; then we have,

ml = 0,+/- 1 and +/- 2; each one of them has 2 electorns, then 2+2+2 = 6 electrons are possible

c)

if ml = -1

then

it can only have +1/2 and -1/2 electrons in spin, therefore, only 2 electrons is the answer

d)

same as in c

ml = +1

then the +/- 1/2 will be the answer o 2 electrons

0

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 = + ½ n=3, l = 2 n=2, l = 1

what is the maximum number of electrons in the atom
that can have the following quantum numbers
1). n=3 and magnetic quantum= -2
2). n =4 and l=3
3). n= 5, l=3, and magnetic quantum=2
4). n=4, l=1 and magnetic quantum=0

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.

For these quantum numbers, determine the number of electrons an
atom could have.
a) n=3
b) n=4 l=2
c) n=6 l=2 ml=-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 (ℓ), the magnetic quantum number (mℓ), 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,...
