Q.
Hund's Rule states that:
No two electrons in an atom can have the same set of four quantum numbers
The maximum number of electrons in the shell with principal quantum n is equal to 2n2
Pairing of electrons in the orbitals belonging to the same subshell (p, d or f) does not take place until each orbital belonging to that subshell has got one electron each i.e., it is singly occupied
None of these
