Each main energy level (1 to 7) has at least an s-orbital,
p-orbitals are possible from the second level onwards (2 to 7)
d-orbitals from 4th level
f-orbitals from 6th level
The s orbital has the lowest energy level.

The s orbital from the energy level resembles a sphere. It is the lowest energy orbital in an atom and has a symmetrical spherical shape around the nucleus.
It has a lower energy level. All else being equal, electrons tend to go into the lowest energy orbital with space available.
the innermost energy level has the least amount of energy
The s orbital is lower in energy than the porbital.
S sub-shell has only one orbital. So, the 2nd energy level has only one s orbital.
Magnesium (Mg) has two electrons in it's lowest (s) orbital.

The lowest energy level that has F orbitals is the fourth energy level. The Atomic orbital of any atom only contains 2 electrons.
The size of an s orbital increases with increasing principal energy level. This means that an s orbital in a higher principal energy level will be larger (have a larger average distance from the nucleus) compared to an s orbital in a lower principal energy level.
