How many electrons are in the first shell of a oxygen atom?

The electron configuration of an oxygen atom is (2, 6). Meaning it has 2 electrons in its first shell and 6 in its second.The energy levels of atoms are limited to how many electrons they can hold.The first energy level can only hold a maximum of 2 electrons the second has a maximum of 8 and the third has a maximum of 18 etc.Hope this Helps!
