Rotate water, methane, carbon dioxide, ammonia, and an ionic crystal model. Watch shape become chemistry.

Molecule Explorer

Look for the bend. That shape helps explain why water is polar.

Rotate the molecule

Water

H₂O

Drag to rotate. Scroll or pinch to zoom.
H₂O

Bent

Bond angle: about 104.5°

Water is not straight. Oxygen has lone pairs that push the hydrogen bonds into a bent shape.
