H2 is deuterium.
And H3 is tritium.
Now, the reason that they get their own distinct name is because,
they are the most distinct from each other as any isotopes.
Isotopes generally have all the same very similar, similar properties.
Their chemical properties are the same, the fact that these have completely
by putting in one more neutron, you've suddenly doubled the mass of
the atom putting in two you've tripled the mass of the atom.
It gives it characteristically different, some very different properties.
And we won't go into all of that, but it does.
Okay, so now we need to focus in on the electrons.
If you lose electrons or gain electrons to an atom, you will create an ion.
Notice you, I don't say that you would add or
remove protons, because you can't get into that nucleus.
And with a chemical process, touch those protons or neutrons.
So an ion is always formed by electrons, these that are being lost or gained.
So the definition of an ion would be a charged species.
So it has a charge, and it's formed by taking a neutral atom or
molecules and either gaining or losing electrons.
So, it's important that we note the electrons.
