What is the Hund's electronic configuration of 2s^2 2p^4?

Answer:

2s: +-, 2px: +-, 2py: + ..., 2pz: + ...

Explanation:

In each energy level there is only one s orbital. One orbital holds two electrons spinning in different directions, + and -. So 2s is filled with a + and a - electron. In each energy level there are three p orbitals. Hund's rule states that each orbital first is filled with one electron and when all orbitals contain one electron the electrons will start filling the rest of the orbitals. Hence, the px: +-, py: +..., and pz: +... .(The ... symbolizes an empty space.)
