Which of the following correctly summarizes the Hund's Rule? Matter can neither be created nor destroyed. It only changes form during chemical reactions. It is fundamentally impossible to know both the location and velocity of an electron at the same time. Each electron within an atom will have its own unique set of four quantum numbers. Electrons orbiting an atom fill the lowest available energy levels prior to filling higher energy orbitals. The ground state or lowest energy state of an atom is the one that contains the maximum number of unpaired electrons.
