when a bond is formed then the forces of attraction are dominant to the forces of repulsion.for a chemical bond to be formed this is compulsory.
In a covalent bond electrons are shared.
Particles formed from the covalent bonding of atoms are called molecules.
H2O (water) is a covalent compound, as no metals are involved.
polar covalent - use the electronegativity difference
Atoms involved in covalent bonding are just called atoms. Molecules are composed of covalently bonded atoms.
Covalent bonds are made up of just Non-Metal atoms, for example, water is a covalent bond in which the chemical formulae is (H2O)
Because mass is always positive. If one of the two objects involved gravitationally were composed of negative mass, then the force would be repulsive.
Covalent bonding.
The gravitational force is proportional to the product of the two masses involved. The product is always positive, since mass is always positive. The electrical force is proportional to the product of the two charges involved. The product can be positive or negative, since either charge can be positive or negative.

Hydrogen is involved in covalent bonds but sometimes also in ionic bonds.

The strong nuclear force is an attractive force that counteracts (or rather balances-out) the repulsive coulomb force. Forces can be modelled by an exchange of particles between the involved bodies. I think the particle responsible for the strong nuclear force is the gluon. In a nucleus there should be a balance of protons and neutrons; too many protons and the repulsive force will be too high, too many neutrons and there won't be enough glue to go round.

A covalent bond is a bond that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.
