Which statement is consistent with Hunds rule ?
AElectrons fill orbitals with parallel spins until all the orbitals of the same energy are half filled then they go into sub-shells with anti-parallel (opposite) spin.
BThe electrons in the same atom cannot have the same four quantum numbers
CNone
DThere is maximum of two electrons is an orbital.
Correct answer
A. Electrons fill orbitals with parallel spins until all the orbitals of the same energy are half filled then they go into sub-shells with anti-parallel (opposite) spin.
Explanation
Electrons fill orbitals with parallel spins until all the orbitals of the same energy are half filled then they go into sub-shells with anti-parallel (opposite) spin. is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
