There are 4 orbitals in H2O , one s and 3 p
That is related to the relative positions of the orbitals involved.
5 orbitals
7 Orbitals
The oxygen in H2O has sp3 hybridization, where one s orbital and three p orbitals combine to form four sp3 hybrid orbitals. This allows the oxygen atom to form four sigma bonds with the two hydrogen atoms and two lone pairs of electrons.
When two atomic orbitals interact, they produce two molecular orbitals.
16 orbitals
Ne has three p-orbitals.
Beryllium has four orbitals in its electron configuration.
The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.
In theory all elements have all the orbitals. Zinc has electrons in four of them.
In H2O, the central atom is Oxygen atom and it is sp3 hybridised
There is one s orbital and three p orbitals and five d orbitals in the third energy level.
