When two atomic orbitals interact, they produce two molecular orbitals.
16 orbitals
Ne has three p-orbitals.
There are 4 orbitals in H2O , one s and 3 p
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.
There is one s orbital and three p orbitals and five d orbitals in the third energy level.
All p sublevels contain three orbitals, including the 4p sublevel.
The number of molecular orbitals in the system depends on the number of atomic orbitals that are combined. If two atomic orbitals combine, they form two molecular orbitals: a bonding orbital and an antibonding orbital. So, in general, the number of molecular orbitals in a system is equal to the number of atomic orbitals that are combined.
