Question

The major binding force that binds diamond,silicon and quartz is
A.Electrostatic force
B.Electrical attraction
C.Covalent bond force
D.Non covalent bond force
E.Vanderwall's force

Answer 1

The above mentioned diamond and silicon belong to the carbon family and quartz is nothing but a mineral that has a network of silicon and oxygen atoms. Binding force is the energy that is required to separate a particle from the other. The stronger the bond, more is the energy required to break it. Bonds are actually formed depending on the nature of the element.

Complete answer:
Let us have a deep idea of different kinds of forces that exist.Electrostatic force is that force which keeps the particles attracted or repelled which is based on the charges. Electrical attraction is basically a force that keeps the atoms together. Covalent bond is formed when the atoms mutually share electrons with each other. Non covalent bonds are formed when they completely exchange the electrons or deny to do it. Van Der Waals forces are the weakest forces. Diamond is formed by the repetition of carbon atoms which are further joined to other four carbon atoms and thus forming a stronger linkage. In silicon and quartz, one atom of silicon is linked with four oxygen atoms thus forming a strong bond.Covalent bond is formed when two nonmetals share electrons among them as in the case of diamond and silicon.

The correct answer is covalent bond force C.

Note:
We know the fact that diamonds are very hard to break. It is because of the stronger covalent bond present between them which requires more energy to break and that is the reason for its higher boiling and melting point. The number of electrons present in the outer shell determines the number of atoms that will make a covalent molecule.
