What are the 3 rule the govern the filling of atomic orbitals by electrons?

  • Chemistry -

    1.I don't know how many rules you have been given but here are some.
    a. Lowest n fills first
    b. s before p before d
    c. Hund's rule of maximum multiplicity(;i.e., don't pair electrons until the set of p,d,f, etc are at least filled.

    There is some juggling that goes on for the b rule and sometimes some juggling for rule c.
