X-rays

 X-rays are produced when excited atoms return to the ground state.

X-rays travel in waves. The number of waves that pass a point in one second is the frequency of the x-ray.

Different elements emit different frequencies of x-rays. The frequencies of the x-rays emitted by the elements are proportional to the squares of the atomic numbers of the elements.

If every deuton and triton of an atom is bonded to every other deuton and triton, the total number of these bonds would be:

# of bonds = ½ z (z − 1)

z is the atomic number of an element. z (z − 1) is pretty close to z squared.

This is evidence that every deuton and triton of an atom is bonded to every other deuton and triton..
