Question

State the rules for electrons in sublevels that are being violated in each of the

following orbital diagrams. If the diagram is correct, write none.

Answer 1

a) none

b) Aufbau Principle: 2s orbital must be filled completely before the 2p orbital

c) Hund's Rule: the electrons must be placed parallel to each other first in all of the 2p orbitals before going back and adding the second electron with opposite spin

d) Pauli Exclusion Principle: Each orbital can only hold a maximum of 2 electrons but the must be in opposite spin not like 3s

e) Aufbau Principle: similar to b, 2p must be filled first.
