Question 3 (Multiple Choice Worth 2 points)

How many electrons in an atom can share the quantum numbers n = 2,l = 1?

1
3
6
10





Question 9 (Essay Worth 3 points)

Explain why the quantum number set (2, 1, -2, -½) is not possible for an electron in an atom.

Answer 1

can anyone help me please i need these answers badly

Answer 2

Ans should be 3 for the first one coz the value of m will be -1,0,1
So it will represent 3 different electrons

Answer 3

And for the second it says l=1 and m= 2 is impossible coz modulus of the value of m can never be greater than l

Answer 4

And in the first one if we consider the spin also i.e. +1/2 and -1/2 both then there can be 6 electrons with same n and l
