If l=0, the only possible value for ml would also be 0, right?

Question

I have a question asking the number of electrons in an atom with the following quantum numbers:

 

n=2 

l=0

m_l=+1

m_s= -1/2

 

since l=0 the only possible value for m_l would also be 0, wouldn't it? Considering the restriction that m_l can only be -l to +l?

Is this a trick question..?

Answer 1

It may be a trick question, but you are correct.  m_l goes from -l to +l so if l = 0, m_l can only be 0.  The number of orbitals will be 1, but the value of m_l will be 0.
