However, not all chemical bonds are created equally, as you will see in the case of ionic vs. Explore the difference between ionic and covalent bonds by looking at each different bond and how it forms. Do you use table salt? Table salt is created from an ionic bond. Ionic bonds form when two oppositely charged atoms called ions trade their electrons negatively charged particles to create a secure bond between the two.

The key thing to remember in an ionic bond is that those electrons are traded to create balance between the two ions hence the ionic bond. However, these bonds will dissociate into ions in water. This happens when you create saltwater.

Rather, covalent bonds are created when atoms share their electrons. You both need it so rather than go without it, you share it instead. Covalent bonds happen between two nonmetals. Hydrogen H has one electron in its outer shell, but it wants eight. Chlorine Cl has seven electrons in its outer shell, but it also wants eight. Search for:. Comparison between Covalent and Ionic Compounds.

Learning Objective Identify element pairs which are likely to form ionic or covalent bonds. Key Points Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds.

Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
