Question

Explain how a covalent bond is different than an ionic bond. Which type of bond is the stronger of the two bonds? Give examples of molecules that are formed by each type of bond.

Answer 1

 Bonds hold atoms and molecules of substances together. There are several different kinds of bonds; the type of bond seen in elements and compounds depends on the chemical properties as well as the attractive forces governing the atoms and molecules. The three types of chemical bonds are Ionic bonds, Covalent bonds, and Polar covalent bonds. Chemists also recognize hydrogen bonds as a fourth form of chemical bond, though their properties align closely with the other types of bonds.

Answer 2

A covalent bond is a bond between 2 non-metals (sharing of electrons between atoms), where ionic is between a metal and a non-metal (the transfer of electrons). Standard covalent bonds are usually weaker then ionic bonds. 

Covalent - Hydrogen + Chlorine = Hydrogen Chloride (HCl)

Ionic - Sodium + Chlorine = Sodium Chloride (NaCl)
