Answer #1

What is the maximum number of electrons in an atom that can have
the following quantum numbers?

**Express your answer as an integer.**

part A. *n* = 3, *m**l* = -2

n =3 so l = 0,1,2 and ml = -2,-1,0,1,2

so ml=-2 represents one orbital which can have max 2
electrons

part B. *n* = 4, *l* = 3

n=4 and l=3

so it must be 4f

maximum electrons = 14

part C. *n* = 5, *l* = 3, *m**l* =
2

n = 5 , so l = 0,1,2,3,4

l =3 so it is 5f and ml=2 so it represents only one orbital so
max electrons = 2

Part D. *n* = 4, *l* = 1, *m**l* =
0

n=4 and l =1

so 4p is the orbital

with ml =0,+1 ,-1

so it represents one p orbital

which can have 2 electrons

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

(c) n = 3, l = 2, ml = -1
(d) n = 4, l = 3, ml = +1

No explanation, just answers

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.

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

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

Part C
The quantum state of a particle can be specified by giving a
complete set of quantum numbers (n,l, ml,ms). How many different
quantum states are possible if the principal quantum number is n =
4?
To find the total number of allowed states, first write down the
allowed orbital quantum numbers l, and then write down the number
of allowed values of ml for each orbital quantum number. Sum these
quantities, and then multiply by 2 to account...

Question 3
Part B:How many values of ml are possible for an
electron with orbital quantum number l = 1?
Express your answer as an integer.
Part C
The quantum state of a particle can be specified by giving a
complete set of quantum numbers (n,l,
