This detailed side-by-side chemistry comparison poster explains ionic bonds (electron transfer, metal + nonmetal, forms ions, crystalline lattice, NaCl example) vs. covalent bonds (electron sharing, nonmetal + nonmetal, forms molecules, H₂O example with bent geometry and polarity). A quick comparison table summarizes formation, elements, particles, force, state, conductivity, and melting point for both bond types. Perfect for: • High school chemistry and AP Chemistry bonding units • Chemical b
