Answer:
The maximum number of electrons an orbital may contain is 2 electrons.
Step-by-step explanation:
There are 4 atomic orbitals called s, p, d and f.
There are one orbital s and it has 2 electrons.
There are three orbitals p, each one contain 2 electrons and in total they have 6 electrons.
There are five orbitals d, each one contain 2 electrons and in total they have 10 electrons.
And there are seven orbitals f, each one contain 2 electrons and the maximum number of electrons this orbital can contain is 14 electrons.
