Source of the Diversity in the Universe

There are 109 elements that so far have been identified. The entire universe, our earth, and all animate and inanimate beings are formed by the arrangement of these 109 elements in various combinations. Thus far, we saw that all elements are made up of atoms that are similar to each other, which, in turn are made up of the same particles. So, if all the atoms constituting the elements are made up of the same particles, what then is it that makes the elements different from each other and causes the formation of infinitely diverse matters?
It is the number of protons in the nuclei of the atoms that principally differentiates the elements from each other. There is one proton in the hydrogen atom, the lightest element, 2 protons in the helium atom, the second lightest element, 79 protons in the gold atom, 8 protons in the oxygen atom and 26 protons in the iron atom. What differentiates gold from iron and iron from oxygen is simply the different numbers of protons in their atoms. The air we breathe, our bodies, the plants and animals, planets in space, animate and inanimate, bitter and sweet, solid and liquid, everything… all of these are ultimately made up of protons, neutrons and electrons.
