Dot-and-cross diagram of water (H₂O)

An example figure from the Dot-and-Cross Diagram generator.

Dot-and-cross diagram of water: an oxygen circle overlapping two hydrogen circles, a dot and a cross in each overlap, and two lone pairs of dots on the oxygen
A dot-and-cross diagram of a water molecule, H₂O, outer shells only. The oxygen atom’s circle overlaps each hydrogen atom’s, and each overlap holds one shared pair: a dot from the oxygen and a cross from the hydrogen. The oxygen’s two lone pairs of dots sit on its own circle, so it has 8 electrons and each hydrogen 2.

Answer key

  • O: 2 bonding pairs, 2 lone pairs
  • Each H: 1 bonding pair, no lone pairs
