What is the maximum number of spdf in chemistry?

Answer 1

The number of orbitals in electron shells are:

One s orbital

three p orbitals

5 d orbitals

7 f orbitals

every shell has an s orbital, only shells 2 and above have p orbitals, only shells 3 and above have d orbitals only shells 4 and above have f orbitals.

Each orbital can hold a maximum of 2 electrons.

Level by level the orbitals

1s (one)

2s, 2p(three)

3s, 3p, 3d (five)

4s, 4p, 4d 4f(seven)

In a shell where they are possible, all three p orbitals have the same energy, all 5 d orbitals have the same energy and all seven f orbitals have the same energy.

I do not like the idea of saying there is a maximum-- an orbital is a solution to the energy levels in a hydrogen atom. You simply cannot have less than 3 p orbitals for instance.
