Question

4. Answer the following questions: (diff=3) a. For n = 4, what are the possible values of the angular momentum quantum number, l? b. What subshells are possible within n = 4? c. For l = 2, what are the possible values of the magnetic quantum number, ml? d. What orbitals do these l and ml values correspond to? e. If ml is 2, what are the possible values for l ? f. What is the maximum number of electrons that can occupy the 3d subshell?

Answer 1

4)

a)

for n=4, l can take values from 0, 1, 2 and 3

Answer: 0, 1, 2, 3

b)

l=0 is for s orbital

l=1 is for p orbital

l=2 is for d orbital

l=3 is for f orbital

possible subshells are 4s, 4p, 4d, 4f

Answer: 4s, 4p, 4d, 4f

c)

for l=2,

ml can be -2, -1, 0, 1, 2

Answer: -2, -1, 0, 1, 2

d)

l=2 is for d orbitals

So, it corresponds to all 5 d orbitals

e)

for ml = 2, l should be greater than or equal to 2

Answer: greater than or equal to 2

f)

3d shell has 5 subshell with ml values of -2, -1, 0, 1, 2

Each subshell can have 2 electrons

So,

number of electrons = 5*2 = 10

Answer: 10
