Singe, double, and triple bonds
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
A chemical bond that may be ionic where the atoms bonded together are charged or covalent where electrons are shared. The nature of the bond depends on the relative electronegativity of the atoms involved. An example of an ionic bond is in sodium chloride. An example of a covalent bond is one between carbon and hydrogen for example in a hydrocarbon. When an element atom bonds to another atom of the same elemnt then that bond is covalent, eg O2, N2, H2, S8.
Yes, O2 is a covalent bond. 8 valence (outer-shell) electrons is a stable configuration, which is what every atom is trying to achieve. There are only 6 valence electrons in one single oxygen atom, which means it is looking for another two valence electrons. Since both oxygen atoms don't want to lose any valence electrons but want to gain two valence electrons, this means that they must each share two of their own with the other atom. Hence both atoms then have eight valence electrons. But because of their sharing electrons, they are stuck together because neither wants to lose their own two valence electrons. This is a covalent bond.
Covalent bonds are when two or more atoms share electrons to receive perfect valence electron shells. So for example, H20, two hydrogen, with one valence electron, and one oxygen with six to form a perfect bond.

Covalent bond
Valence electrons occur in the outermost shells of an atom. Valence electrons can be shared in covalent bonds. Covalent bonds occur between non-metals, like Carbon and Nitrogen.
In a covalent bond electrons are shared between two electrons.
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
a chemical bond in which valence electrons are shared between atoms giving each of them a full valence shell is a covalent bond.
