Calcium has 2 outer ring electrons, while oxygen has 6 outer ring electrons.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
I donno,But there is 8 protons :D <3
Oxygen has 6 valence electrons. These are in the outer orbit.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
An oxygen atom has six (6) electrons in its outer shell.
There are 6 electrons in the outer shell of CH2O. Carbon has 4 outer electrons, hydrogen has 1 each, and oxygen has 6.

Oxygen has 6 electrons in its outer shell. It belongs to group 16 of the periodic table, also known as the oxygen family or chalcogens, and has 6 valence electrons.
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.
8 all together
it has 6 electrons in the outer most shell
