Arrange: Click Next element to select carbon. Add a second electron to the first 2p orbital. Click Check. What feedback is given?6. Rearrange: Hund’s rule states that electrons will occupy an empty orbital when it is available in that subshell. Rearrange the electrons within the 2p subshell and click Check.

Explanation:

The correct electronic configuration for carbon is;

1s2 2s2 2px1 2py1 2pz0

Carbon has six electrons in its outermost shell. According to Hund's rule, electrons will occupy all the empty orbitals when they are available in that subshell.

Hence, if you attempt to add a second electron the the first 2p orbital (2px), the arrangement of electrons will be flagged as incorrect. The other 2p electron must be added to the second 2p (2py) orbital.
