Summary Introduction

Introduction:

A chemical bond occurs when the electrons are transferred or shared between the two atoms by attraction. Many atoms get more stable when their valence shell is filled with electrons and this leads to create chemical bonds with each other. Because electrons only determining the bonding with other atoms. Here, electronegativity is the main reason to increase the ability of an atom to attract electrons. There are three important types of chemical bonds can occur in the living organisms such as ionic bond, covalent bond, and hydrogen bond.
