Why is the s orbital fill before the p orbital?

The s orbital fills before the p orbital because it has lower energy, and is more stable.


Why does an s orbital fill before a p orbital?

In general, electrons fill up different positions in such a way that they are in the lowest possible energy level. The orbitals closer to the nucleus have a lower energy level than the ones which are further out.


Combination of one s orbital with one p orbital?

s orbitals are spherical, so there cannot be any angle 'between' an s orbital and a p orbital. However, each lobe of a p orbital is perpendicular (90 degrees in all directions) to the surface of an s orbital.

How many atomic orbitals must be mixed to make the sp2 hybrid orbital?

five atomic orbitals must be mixed into one ; one s orbital; three p orbital; one d orbital, forming sp3d orbital


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

Why is helium stable with a different arrangement?

All noble gases have completely filled orbitals. Helium has two valence electrons and its s-orbital is full and is stable. Other noble gases have completely fill p-orbitals as the valence orbitals.
