What are major differences between covalent and ionic bonds?

<p>The name of covalent and ionic bonds tell their formation story in small detail. <strong>Co</strong>- means sharing or coexisting, so whenever there is bond fromation due to <strong>sharing of valence electron, &nbsp;</strong>it is known as <strong>covalent bond</strong>. Similerly, ionic bonds suggest that when a bond formation takes place due to <strong>ions, which attract each other</strong>, it is considered as <strong>ionic bond</strong>. Ionic bonds are also known as electrovalent bonds. There are some major differences between Electrovalent and covalent bonds.
