It should be 2.6 The inner shell is full with two, and the next shell only contains six. When it becomes an ion, it gains two electrons which are negatively charged to make it O2-.
Oxygen is a non metal element. There are 8 electrons in a single atom.
electrons
A neutral atom of oxygen would have 6 valence electrons.
Electrons are arranged around the atomic nucleus forming the electron clouds.
Oxide is the ion form of oxygen. It forms when an oxygen atom gains an extra two electrons. So an oxide ion would become an oxygen atom by losing two electrons.
Oxygen is a chemical metal element. There are 8 electrons in a single atom.
Electrons are arranged in shells around the atom.
electrons are shared in two shells, 2 in the first and 6 in the second
electrons are arranged in energy levels, or shells, around the nucleus of an atom.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Electrons are arranged in shells, subshells and orbitals.
Every oxygen atom has eight electrons.
In an Oxygen Atom there are two rings on which the Electrons orbit around the Nucleus, there is the inner ring and the outer ring. The inner ring closest to the Nucleus contains two Electrons and on the outer ring there are six Electrons making a total of eight Electrons, which is equal to the amount of Neutrons and Protons in the Nucleus (8 Neutrons, 8 Protons). This should answer the Question.
Every oxygen atom has eight electrons.
electrons
An oxygen atom has two valence electrons.
Oxygen's atomic number is 8. That means an atom of oxygen always has 8 protons. To stabilize it then, it must also have 8 electrons.
