Question

If 4 electrons are available to fill three empty 2p atomic orbitals, how will the electrons be distributed in the three orbitals

Answer 1

The first orbital will have 2 electrons, and the other two will have only 1 electron. So, strat filling each orbital with 1 electron,  and when they each get one, then start over, so for 4 electrons, the first one will have 2 electrons in the orbital.
