* Covalent bonds: These bonds form when two atoms share electrons. This sharing creates a strong attraction between the atoms, holding them together. Covalent bonds are the strongest type of chemical bond.
* Ionic bonds: These bonds form when one atom loses an electron and another atom gains an electron. This creates a positive and negative charge on the atoms, which then attract each other. Ionic bonds are typically weaker than covalent bonds.
* Metallic bonds: These bonds occur between metal atoms. Electrons are delocalized and can move freely throughout the metal. This creates a strong attraction between the atoms, making metals strong and conductive.
The specific type of bond that forms between two atoms depends on the types of atoms involved and their electron configurations.
