In this article, we shall study the types of chemical reactions. Before understanding the types of chemical reactions, let us study the meaning of the terms “a physical change” and “a chemical change” Physical Change: A change in which only the physical properties of a substance are changed is called a physical change. In a […]

No Comments on Ionic Bond or Electrovalent Bond

The electrostatic force of attraction between the oppositely charged ions is called the ionic bond or electrovalent bond. This bond is formed between two atoms whose electronegativity difference is large and they can attain octets by the complete transfer of one or more electrons from one atom to another. The atom which loses electrons is […]

In a chemical reaction, one or more substances, called reactants undergo a chemical change to produce new substances called products of the reaction. Thus a chemical reaction is a process in which reactants undergo a change to produce products. Reactants: One or more substances which react and undergo chemical change are called reactants of the […]
