An easy way to describe Deuterium is that it is a Hydrogen atom plus one more neutron inside the nucleus of the Hydrogen. For example if there are two neutrons inside the Hydrogen atom it is called Tritium, as the mass number (total number of protons and neutrons inside the nucleus) is 3. For neutral Hydrogen it is 1, for there is only one proton makes up its nucleus. I hope this is clear. As more neutrons get added to the nucleus, they are called isotope of the atom in question. I hope this explains it. | |
