Answer 1

Answer:

hi

The electron configuration can be written as 1s22s22p4. ... That leaves 4 electrons, which must be placed in the 2p orbitals. According to Hund's rule, all orbitals will be singly occupied before any is doubly occupied. Therefore, two p orbital get one electron and one will have two electrons.
