An oxygen atom has 6 electrons in its outer shell, therefore it needs two more to have a stable configuration of 8 electrons. That's why the valence is two.
An oxygen atom has two valence electrons.
O - Oxygen has 6 valence electrons.
two , two valence electron Oxygen has two valence electrons since it must gain two in order to obtain 8 electrons in its outermost energy level. However, the number of valence electrons is six--not two. The valence and valence electrons are only the same for metals in Groups 1, 2, and 3.
Oxygen has a valence of 2 in a water molecule, while hydrogen has a valence of 1. This allows for the formation of two covalent bonds between the oxygen and the two hydrogen atoms in water (H2O).
A neutral atom of oxygen would have 6 valence electrons.
six valence electrons.....It only requires two more to complete octet....
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
H2O2 is one of the exceptions to the normal valence of -2 for oxygen. In H2O2, there is an oxygen-oxygen covalent bond, and therefore, although the valence of oxygen is still two, one of the bonds has no charge so that the charge of oxygen is only -1.
First of all, what "are" the electrons in oxygen.Oxygen has 6 valence electrons (the electrons in the outer shell or in other words, the electrons that will react). Since every atom wants to have 8 valence electrons, then oxygen will want to gain 2electrons. Therefore it will use two of it's electrons to form bonds. Oxygen always forms two bonds with two lone pairs. :ö= or -:ö-
Valence electrons are shared between oxygen atoms, Four valence electrons are shared.
It has a negative charge which means its -2 :) Hope this answers the question!
Oxygen has six valence electrons. So each oxygen atom needs two more valence electrons, which it will acquire by sharing them with another atom, in this case, another oxygen. Each oxygen atom will share two of its electrons, forming a double bond, in order to jointly complete both its own and the other oxygen's valence shell. The other four valence electrons do not join in the covalent bond.
