Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore
