The statements. (i) In filling a group of orbitals of equal energy, it is energetically preferable to assign electrons to empty orbital rather than pair placed in two different. (ii) When two electrons are placed in two different orbitals, energy is lower of the spins are parallel, are valid for.

In a set of degenerate orbitals, the electrons distribute themselves to retain similar spins as far as possible. This statement is attributed to :

The energy of an electron in the 3rd orbit of an atom is -E . The energy of an electron in the first orbit will be

When there are two electron is the same orbitals , they have ……………spins
