From the Pauli Exclusion Principle, arsenic can have up to
Well, I don't know, let's say we pick a
- It must be on the energy level given by
#n = 4# . #s# orbitals, spherically shaped, have zero angular momentum, so#l = 0# .- There can only be one
#4s# orbital in existence. For#l = 0# ,#m_l# is limited in range to only the set#{0}# . Each value of#m_l# corresponds to one orbital, and so there is only one. - Every electron can have either spin-up
#1//2# or spin-down#1//2# for the value of#m_s# . Since this orbital is filled already, there is not just one choice.
Thus, one has two options for a
#(n,l,m_l,m_s) = (4,0,0,+1/2)#
#(n,l,m_l,m_s) = (4,0,0,-1/2)#
Maybe you can brainstorm the other
