Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
The innermost shell of every atom except hydrogen consists of 2 electrons.
Oxygen: 6 electrons
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
A neutral atom of oxygen would have 6 valence electrons.
The electron configuration of an oxygen atom is (2, 6). Meaning it has 2 electrons in its first shell and 6 in its second.The energy levels of atoms are limited to how many electrons they can hold.The first energy level can only hold a maximum of 2 electrons the second has a maximum of 8 and the third has a maximum of 18 etc.Hope this Helps!
Oxygen. Two of the electrons are in the first shell. The other six of them are in the second shell.
An oxygen atom has six (6) electrons in its outer shell.
The innermost shell of every atom except hydrogen consists of 2 electrons.
Oxygen: 6 electrons
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.

Because it has 6 electrons in its outer shell, just like oxygen.
A neutral atom of oxygen would have 6 valence electrons.
