"Want" is a word you should try to avoid when talking about atoms. Oxygen reacts to get a full outer shell of 8.
An oxygen atom has six (6) electrons in its outer shell.
8
Oxygen has 6 valence electrons. These are in the outer orbit.
2
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.
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 word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
6
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.
A neutral atom of oxygen has 6 electrons in it's most outer orbit. Generally, if you count horizontally from left-to-right on the periodic table, you get the number of electrons in its' most outer orbit. You start every row with 1, of course. :) Hope that helps!
Oxygen has 6 valence electrons (Electrons in the outer most orbit). However, on the whole, Oxygen has 8 electrons as its atomic number is 8.
Oxygen is a non metal element. There are 8 electrons in a single atom.
