They all have 6 in its outer shell because they are all in the same group in the Periodic Table.
Your VERY VERY welcome (:
they are in the same group in the periodic table so they should be predicted to have six electrons in their outer shell
It needs two more electrons to have a full outer orbital. When it claims the two electrons, it becomes an O2- ion.
Oxygen: 6 electrons

Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
8 electrons on the outer shell
The outer shell of an atom is the valence shell, which contains the valence electrons.
An oxygen atom has six (6) electrons in its outer shell.

Oxygen: 6 electrons

Because it has 6 electrons in its outer shell, just like oxygen.

The two outer shell electrons of a calcium atom are donated to an oxygen atom, forming calcium cations and oxygen anions that together constitute the salt compound calcium oxide.
An electrically neutral oxygen atom has eight electrons, one for each proton in its nucleus. Two electrons are in the inner shell and six are in the outer shell.
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
8 electrons on the outer shell
The outer shell of an atom is the valence shell, which contains the valence electrons.
