Here's why:
* Nonmetals have high electronegativity: This means they have a strong attraction for electrons.
* Sharing electrons: When two nonmetals bond, neither atom has enough strength to completely remove an electron from the other. Instead, they share electrons to achieve a stable electron configuration.
* Covalent bonds: The shared electrons create a strong attractive force between the atoms, forming a covalent bond.
Examples of covalent bonds between nonmetals:
* Water (H₂O): Hydrogen and oxygen share electrons.
* Carbon dioxide (CO₂): Carbon and oxygen share electrons.
* Nitrogen gas (N₂): Two nitrogen atoms share electrons.
