Answer:

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.
