They all have 6 in its outer shell because they are all in the same group in the Periodic Table.
Your VERY VERY welcome (:
An atom of oxygen needs 2 electrons to complete its outer shell, which can hold a total of 8 electrons. Oxygen has 6 electrons in its outer shell, so it will gain 2 electrons through bonding to achieve a full valence shell.
The atom O has 6 electrons in its outer shell, as it belongs to group 16 of the periodic table, also known as the oxygen family.
Oxygen has 6 valence electrons. These are in the outer orbit.
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.
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.
An oxygen atom has six (6) electrons in its outer shell.

The atom O has 6 electrons in its outer shell, as it belongs to group 16 of the periodic table, also known as the oxygen family.
2
Because it has 6 electrons in its outer shell, just like oxygen.
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.
Oxygen has 6 valence electrons. These are in the outer orbit.
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.
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.
When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
