🔷 Symmetry Elements (tap to view • ▶ to animate)
✅ Achiral🧲 Dipole: yes⚛️ 3 atoms🔷 3 elements
📖 Water has a simple bent geometry. Its symmetry elements consist of a 180° rotation axis (C₂) and two perpendicular planes of symmetry passing through the oxygen atom.
🔷 σ_v (yz-plane, Molecular) ✓ verifiedThis plane lies directly in the plane of the water molecule, containing all three atoms (O, H1, H2).
🔷 σ_v\' (xz-plane, Bisecting) ✓ verifiedThis plane passes through the oxygen atom and bisects the H-O-H bond angle, reflecting one hydrogen atom onto the other.
🔄 C₂ Axis <span class="mse-badge mse-b-blue">C2</span> ✓ verifiedA two-fold (180°) rotational axis aligned vertically along the z-axis, passing through the Oxygen atom.

Rule of thumb: no mirror plane + no inversion → possibly chiral. More symmetry → usually zero dipole.
