Question

The magnetic quantum number (m) for an electron in 5d orbital : *
a) can have any values less than five
b) may be zero
c) may be +1/2 or -1/2
d) is four​

Answer 1

Answer:

the answer is option c

Explanation:

The 5d orbital has principle quantum number i.e the shell number=5,

azimuthal quantum number i.e the subshell number=2 (since value of d subshell=2)

For azimuthal quantum number=2,

values of m are -2,-1,0,+1,+2

Hence, the value cannot be 4 or less than 5

So the value may be zero

[Extra:the values in option c indicate spin quantum number(s)]
