Covalent Bond

Real World Example

Imagine two friends who each want to watch a movie, but neither can afford the streaming service on their own. Just like these friends decide to share the cost of the service to both enjoy the movie, atoms in a covalent bond share electrons to achieve stability. In this analogy, the streaming service represents the shared electrons, the friends are the atoms, and the act of sharing ensures that both parties (or atoms) get what they need, which is stability in their respective situations.
