hydrogen bond
Sharing or exchange of electrons.
Those would be the electrons (found "orbiting" the atomic nucleus). Chemical reactions normally involve transfer or sharing of the "outer shell" electrons.
The sharing of electrons via covalent bonds
Breaking of bonds but also formation of new bonds.
It is not clear from your question what you mean by sharing substances, or exactly what it is that these substances are sharing. However, I'll make a guess. Chemical reactions often involve atoms sharing electrons. And what happens to them during chemical reactions is that the distribution of electrons shifts. Electrons don't have to actually leave one atom and go to another in order to form a chemical reaction. Sometimes it is more a matter of spending some time with one atom and some time with another, or with several others. Electrons are very versatile.
Sharing or exchange of electrons.
There are two types of chemical bonds, covalent and ionic. Ionic involve the complete transfer of electrons and covalent involve the sharing of electrons.
There are two types of chemical bonds, ionic and covalent. Ionic bonds involve the complete transfer of electrons from one atom to another. Covalent bonds involve the sharing of electrons between the two atoms.

Molecules or covalent compounds are formed by the sharing of valence electrons.
Chemical bonds can be only produced by gaining, losing or sharing electrons. If a compound is formed by losing or gaining electrons, it is called an ionic bond and if by sharing electrons, it is called a covalent bond.
