O2 has two unpaired electrons. The O atom has two unpaired electrons.
8 electrons
Helium has 2 electrons
Since oxygen is not a metal, its ions are not normally written with Roman numbers suffixed, but an oxide ion, with formula O-2, contains 10 electrons.
As an element oxygen is neutral, but it forms negative ions.
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.
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Number of electrons in oxygen is 8 & that of neon is 10.
Oxygen as 2 core electrons and 6 valence electrons.
The electron configuration 1s2 2s2 2p5 represents an atom of oxygen. The numbers indicate the number of electrons in each energy level and sublevel, showing that oxygen has 8 electrons total.
Oxygen has 6 valence electrons.
Oxygen has 8 electrons in a neutral state.
