The Number of Electrons in the l = 2 Subshell for a 35-electron Atom

[a.a]

If an atom in it's ground state has 35 electrons, then how many of these electrons are in the l = 2 subshell?

 

[Borek]

How are electrons assigned to different shells?

 

[a.a]

by their energy leveals?
im not very clear on this topic
