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 innermost shell of every atom except hydrogen consists of 2 electrons.
Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
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.
A neutral atom of oxygen would have 6 valence electrons.
An oxygen atom has six (6) electrons in its outer shell.
The innermost shell of every atom except hydrogen consists of 2 electrons.

Six in the outer (2nd) shell
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.
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.
Because it has 6 electrons in its outer shell, just like oxygen.
A neutral atom of oxygen would have 6 valence electrons.
