ok so am trying to revise electron configuration...heres the question :
Write the electronic configuration of V(3+) using the orbital method
heres the answer :
1s2 2s2 2p6 3s2 3p6 3d2
my question is that shouldnt the 4s2 orbital be filled first because its lower in energy than the 3d orbital and since theres only 2 electrons left filling the 4s2 orbital would make it more stable???
Will Oxford nullify my offer?
