A chemical bond refers to a force that holds atoms together to make molecules. A matter like metal is made of small particles called atoms, and they are joined together by chemical bonds. The type of bond binding the atoms determines the strength of the matter. A chemical bond can be stronger or weaker, depending on the strength of the chemical forces. Some of the common types of bonds include ionic, covalent, polar, and hydrogen bonds.
An ionic bond is the chemical attraction between two ions that form an ionic compound. Ionic bond involves a metal and a nonmetal where the particles attract each other. In this case, the valence electron from the metal is transferred to nonmetals leading to the creation of negative and positive compounds. An example of an ionic bond is evident in the combination of sodium and fluoride. A covalent bond involves a combination of two or more atoms to come up with a living organism. Covalent bonds are common when an electron or electrons are shared by different organisms and are common in living things and lead to biological molecules’ formation. For instance, hydrogen and oxygen atoms combine to form water molecules—a polar bond results when two atoms are connected by covalent bonds leading to a weaker charge. Although covalent bonds are stronger, the positive and negative forces associated with them are weaker. A hydrogen bond happens when atoms in covalent bond molecules pull some electrons on one side of the molecules leading to molecular imbalance. A hydrogen bond is also a weaker chemical bond when compared to the two but still important. Hydrogen bond gives the water its distinct characteristics.mm
