An oxygen atom has two shells. The first contains two electrons, and the second contains six electrons.
18 electrons (maximum)
i think 8

Selenium has four electron shells.
5
the no. of electron shells in an atom varies for every element in the periodic table, depending on its no. of electrons in the atom. the no. of shells of an atom of an element ca be derived through the period of the periodic table. elements in the 1st period has only 1 shell and so forth.
3
Only two electron shells.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The largest atom is calcium which has 4 shells.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1
Selenium has four electron shells.
