One or both atoms are a different isotope of Hydrogen, namely Deuterium (""^2"H" a.k.a. "D") instead of Protium (""^1"H").

Explanation:

One or both atoms of Hydrogen in heavy water are Deuterium - the stable isotope of Hydrogen that has a nucleus containing both a neutron and a proton instead of just a proton.

Deuterium (""^2"H" or "D") has similar but not identical chemical properties to the much more common Protium (""^1"H") isotope.
