Answer:
There are three main types of bonds: ionic, covalent and metallic. These bonds occur when electrons are transferred from one atom two another, and are a result of the attraction between the resulting oppositely charged ions. This happens between atoms with an electronegativity difference generally larger than 1.8.
Chemical Bonds are physical phenomenon of Chemical substances
being held together by attraction of atoms to each other thought
sharing,as well as exchanging,of electrons -or electrostatic forces.
