Explain covalent versus ionic bonding as you would to a capable student, in 3-4 sentences.

# Covalent vs Ionic Bonding **Ionic bonding** occurs when one atom completely transfers electrons to another atom, creating oppositely charged ions that attract each other—this typically happens between metals and nonmetals with very different electronegativities (like sodium and chlorine forming table salt). **Covalent bonding** occurs when atoms share electrons between them rather than transferring them, which typically happens between nonmetals with similar electronegativities (like two hydrogen atoms sharing electrons to form H₂). The key difference is that ionic bonds involve electron *transfer* and electrostatic attraction between ions, while covalent bonds involve electron *sharing* between atoms. In reality, most bonds fall on a spectrum between purely ionic and purely covalent, with polar covalent bonds representing the middle ground where electrons are shared unequally.
