An atom of oxygen has 8 electrons.
They are configured as 1s2, 2s2, 2p4.
The 2p4 sub-shell is the outermost shell , and therefore the most energetic.
The '2' shell has 6 electrons leaving space to accept two more electrons.
Two received electrons would be in the 2p sub-shell, making for the complete octet of electrons in the 2 shell.
This would form either a covalent bond with other non-metals or act as an anion to combine ionically with metallic cations.
When oxygen combines covalently with say hydrogen ( a non-metal) the hydrogen atom shares its one electron with one of the 2p4 electrons . This occurs twice over making the shared electrons, from two hydrogen atoms, to complete the 2p sub-shell from sp4, to sp6. This is the case for water (H2O , structurally H-O-H, each hyphen represents two electrons on the covalent bond.
When oxygen combines ionically, it receives two electrons from a metal atom that has ionised e.g. 2Na ==> 2Na^+ + 2e^- These two electrons move to the oxygen atom under the influence of electron affinity. So it completes the 2p sub-shell. to 2p6.
The oxygen anion (O^2-) the combines ionically with two sodium cations (2Na^+) Opposite charges attract.
Hence we have Na2O.
Hope that helps!!!!
O - Oxygen has 6 valence electrons.
Oxygen has 6 valence electrons.
A neutral atom of oxygen would have 6 valence electrons.
six valence electrons.....It only requires two more to complete octet....
Oxygen (O) has 6 valence electrons and fluorine (F) has 7 valence electrons. In OF2, there are a total of 18 valence electrons (6 from oxygen and 2 x 7 from fluorine).
O - Oxygen has 6 valence electrons.
6 Valence Electrons
Oxygen has 6 valence electrons.
Oxygen has six valence electrons.
Oxygen has 6 valence electrons. A person can determine the number of valence electrons by looking at the periodic table. since oxygen is in the 6th column form the left, it has 6 valence electrons.
Oxygen has 6 valence electrons.
A neutral atom of oxygen would have 6 valence electrons.
Oxygen has 6 valence electrons.
All have six valence electrons.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
Oxygen has six valence electrons.
Oxygen as 2 core electrons and 6 valence electrons.
