The lightest element, hydrogen, has one proton, whereas the heaviest naturally occurring element, uranium, has 92 protons. Isotopes are each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.

Most of the rocks we see on the surface of the planet formed by processes that happened long ago, but we can see these processes actively taking place in many places.For instance, rocks and minerals formed deep underground may not be stable in the surface environment where they are exposed to water, air, temperature changes, and other physical and chemical conditions.All matter is made up of atoms, and atoms are made up of atomic particles (electrons, protons, and neutrons - see Figure 2-5).For example, the element carbon has 3 isotopes: C is unstable and will undergo radioactive decay.All there isotopes have 6 protons, but have 6, 7, and 8 neutrons, respectively.In contrast, minerals considered "gems" are, mostly, exceedingly rare.A rock is a relatively hard, naturally formed mineral or petrified matter; a naturally formed aggregate of mineral matter constituting a significant part of the earth's crust.Basic concepts of chemistry are essential to understanding the physical and chemical properties of earth materials (minerals, rocks, organic matter, etc.).The chemical characteristics of earth materials are reflect the environments how and where they are formed, they also determine their potential fate when exposed to chemical changes.Rocks are composed of chemical compounds naturally occurring in nature.Rocks are composed of particles ranging from microscopic grains to full sized crystals and crystal grains of different kinds of minerals, and containing many different identifiable physical characteristics.
