Ionic bond examples: Diagram of a molecule of salt, which uses an ionic bond When atoms get close together, sometimes they form ionic bonds that stick them together into molecules. These ionic bonds are generally stronger than covalent bonds. Unstable atoms form ionic bonds Some kinds of atoms, like sodium, have only one [...]

Covalent bonds: two hydrogen molecules bonding to an oxygen molecule Covalent bonds stick atoms together When two atoms come near each other, sometimes they stick together to make a molecule. One way they can stick together is by covalent bonding. Ionic bonding More about molecules What are atoms? All our chemistry articles Are covalent [...]
