. All orbitals of a given degenerate (or equal energy) set must be singly occupied before pairing begins in that set is a statement of:1 pointPlanck's theoryHund's rulethe Aufbau principlethe Heisenberg's uncertainty principlethe Bohr theoryPauli's exclusion principle

Statement-I: The orbitals having same energy are called as degenerate orbitals.

In Bohr's model of the atom, electronsGroup of answer choicesonly make transitions between orbitals of specific energies.move from orbit to orbit in many small steps.are spread uniformly through a large, positive mass..can be halfway between orbits.are not confined to specific orbits.

10. Which explains the filling up of the orbital in the order of increasing energy?A. Octet RuleB. Hund’s RuleC. Pauli’s ExclusionD. Aufbau Principle

1s7 electronic configuration is not observed because it violates ans. Pauli’s exclusion principle Bohr’s theory Aufbau principle Hund’s rule

Hund’s Rule predicts thatGroup of answer choiceselectrons occupy all the orbital of a given subshell singly before pairing begins.electrons must have opposite spins to share an orbital.electrons in an orbital have equal but opposite charges.no two electrons will share the same orbital.
