This interactive activity from ChemThink describes covalent bonding—a type of chemical bond that involves the sharing of electrons. Investigate the attractive and repulsive forces that act on atomic particles and how the sharing of electrons can keep atoms together. See how two hydrogen atoms interact with each other to create a covalent bond. Learn about trends in the periodic table and how electrostatic potential energy determines the bond length. Also, learn about naming conventions for covalent compounds.
Follow the instructions closely as you move through this activity! There are some screens where you have to do something before you can move onto the following screen.
- Atoms gain stability when they share electrons and form covalent bonds
- When only one pair of electrons is shared, the result is a single covalent bond
- Double bonds form when two pairs of electrons are shared between two atoms
- Triple bonds form when three pairs of electrons are shared between two atoms
- The strength of the bond increases and the distance between the two nuclei decreases
