In what order do electrons fill orbitals within the 3p sublevel? Electrons don’t fill orbitals; protons and neutrons fill orbita
lorasvet [3.4K]

 The order  do electron fill  orbitals within the 3p sublevel  is that they spread  out, waiting  until each orbital  has one electron before  doubling  up.


<u><em>Explanation</em></u>

<u> </u> According    to   hund's  rule  every orbital in a   subshell  is singly  occupied  with  one  electron before  any one orbital  is  doubly  occupied,and  all electrons  in   singly occupied  orbital have the same spin.

when every orbital  in a subshell is   singly  occupied by electrons it is then  doubled, and the two electrons  in same orbital  have  opposite spins
