Measured.

What is the difference between a solid, a liquid, and a gas - but
dispersion of atoms or molecules. With further increase in temperature can
atoms disperse/split?

Non radioactive nuclei are forever unless involved in nuclear
reactions.


Conversely, is a drop in temperature needed for some elements to form?

Nope.


Hydrogen constitutes only a small percentage of the Earth's crust - now.
But that is because most hydrogen on earth is tied up in water, and in
living things.

You are more hydrogen than anything else.

If hydrogen is the most primitive element, and Nature is a causal
process, then it is reasonable to assume all the other elements came from
primitive hydrogen. Unless they were all formed simultaneously, and
immutably.

No, most He, Li came out of the big bang.
