knows the answer. Normal Hydrogen has a proton in the middle (and
its electron whizzing around outside but heavy hydrogen has a special
nucleus with a proton and a neutron as well. This nucleus makes
the type of heavy hydrogen called Deuterium. But that is not all.
There is a third type of hydrogen which has TWO (count 'em) neutrons
as well as the proton in the middle. this one is caled - you guessed
it - Tritium. All of these types of hydrogen behave pretty much
like normal hydrogen chemically which means that they normally go
around in pairs - H2 gas and they combine with oxygen to make H2O
D2O and T2O but, with all those extra neutrons on board the water
is heavier than normal water - HEAVY WATER. The big difference is
that Deuterium and Tritium are both RADIOACTIVE.
