Ionic vs Covalent Bonding
Compare ionic and covalent bond formation side by side. Four tabs: Ionic (electron transfer animation for NaCl, MgO), Covalent (shared electron clouds for H₂, O₂, N₂), Polar Covalent (dipole arrows for H₂O, HCl), and Properties Comparison table. An electronegativity difference bar chart highlights ΔEN cutoffs at 0.4 and 1.7.
