Question

ample Test D Which of the following correctly summarizes the Hund's Rule? Matter can neither be created nor destroyed. It only changes form during chemical reactions. O It is fundamentally impossible to know both the location and velocity of an electron at the same time. O The ground state or lowest energy state of an atom is the one that contains the maximum number of unpaired electrons O 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. Points possible:1 Unlimited attempts Submit

Answer 1

Answer is c. The ground state or lowest enegy state of an atom is the one that contains the maximum number of lempaired electrons, because this is what Hund's rule of mesimum multiplicity States - electron paining will not take place in orbitals of same energy (same subshell) writid each Dabidal is singly filledo 9+ is difficult for an electron to enter an orbital which already has an electron than to enter an unoccupied Orbital of same energy.
