Why is “heavy water” used in nuclear energy, are not potable to drink, even it’s just 1 molecule more than H2O?

> 1 molecule more than H2O?
If you look at periodic table of chemical elements, difference by mere few electrons can turn things into insanely *different something else*. Like from light gas into heavy metal, from something relatively harmless to something quite radioactive or toxic, and so on.
That’s how chemistry works. Just adding one more oxygen atom to water molecule would turn it from very safe liquid into quite fatal and skin-irritating hydrogen peroxide. Same with heavy water.
