There are two types of chemical bonds. In this case, where electrons are shared among all the atoms, this is a covalent bond.
In a covalent bond electrons are shared between two electrons.
a chemical bond in which valence electrons are shared between atoms giving each of them a full valence shell is a covalent bond.
Covalent bond
Carbon atoms do not gain electrons to form a covalent bond. Carbon atoms form four covalent bonds by sharing its four valence electrons with the valence electrons of other atoms. These can be single bonds, in which one pair of electrons is shared; double bonds, in which two pairs of electrons are shared; or triple bonds, in which three electrons are shared; or a combination of these.
They are either transferred or shared. In ionic bonds, electrons are transferred, and shared in covalent bonds.
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
They are shared by the valence shells of the atoms involved in the bond.

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.
Actually 4 electrons are being shared between 2 atoms. Each atom provides 2 electrons for a total of 4. If only 2 electrons are being shared, it is a single covalent bond.

Metals have metal bonds. valence electron make bonds with metal ions.
