Hi,

Would there be any further state change if i heated H2 to about 100,000 K? 1,000,000 K? What is the hottest temperature possible? I would imagine it would be when the molecules are vibrating at nearly the speed of light? I know temperatures of 1 trillion kelvin supposedly happen when a star goes supernova.

Yes.  Once you get the gas hot enough, the electrons will leave the atoms thus creating the so-called 4th state of matter; plasma.  You'll just have a gas full of hydrogen nuclei.

So you'll just have a proton and a neutron stuck together. Won't they repel that way, since they're all the same charge? I wonder if there's a way to further screw with this superheated gas by knocking that neutron off, and be left with only a cloud of protons...

Almost all hydrogen consists of only a proton with no neutrons. Deuterium (one proton and one neutron) is much less common.

Just as in the Sun

i see, and the sun turns the Hydrogen protons into Helium atoms through Hyrdogen Fusison.

Yes, but when it turns it to helim a lot of energy is also given off.

Also, at that high of a temperature, the kinetic energy of the nuclei will pretty much overcome the electrical repulsion they experience.
