The formula for heavy water is \mathrm{D}_2 \mathrm{O}.

Deuterium contains 1 proton, 1 neutron, and 1 electron.

Oxygen contains 8 protons, 8 neutrons, and 8 electrons.

Hence, \mathrm{D}_2 \mathrm{O} contains 2 D and 1 O atoms.

\mathrm{D}_2 has 2 protons, 2 neutrons, and 2 electrons while O has 8 protons, 8 neutrons, and 8 electrons. 

Hence, \mathrm{D}_2 \mathrm{O} contains 10 protons, 10 electrons, and 10 neutrons.
