Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
Two.
The # of Valance electrons in the oxygen famly is 6
Yes, electrons are transferred between the nitrogen atom and oxygen atoms.
2
Oxygen is a non metal element. There are 8 electrons in a single atom.
One carbon atom will share four electrons.
Each hydrogen atom is bonded to the oxygen atom in a covalent bond, in which they share valence electrons.
Every oxygen atom has eight electrons.
Every oxygen atom has eight electrons.
In a water molecule, the oxygen atom shares electrons with two hydrogen atoms, but it does not share equally since it has a stronger attraction for electrons than the hydrogen atom does, and the electrons therefore have a greater probability of being close to the oxygen nucleus than to the hydrogen nuclei. As a result, the oxygen atom has a negative charge. The hydrogen atoms are positively charged.
An oxygen atom has two valence electrons.
No. They reason it is polar is because one side is slightly positive and the other slightly negative. For this to happen, there needs to be unequal sharing of electrons. One atom will have a higher electronegativity than the other, and will naturally "keep" the electrons longer. So that atom will be slightly negative for having held onto the electron, creating a polar bond.
