Economists (price of base metals, investments, etc. ) A mineral must have the following attributes: naturally occurring formed by geological processes. Inorganic: formed by geological processes, solid (ie. not petroleum, ordered internal molecular structure, definite chemical composition quartz is a good example. Rock: a solid mass of minerals rocks are made of minerals. Mineral: naturally occurring, solid chemical substance formed through geological processes; in addition to the above list it has physical properties (hardness, cleavage, luster, taste/smell, etc. ) Therefor glass, synthetic gems and petroleum are not minerals. To build minerals, the atoms of chemical elements must join by forming bonds. Ununquadium (heaviest element) has an atomic number of 114. Unbiblium (most recently discovered) has an atomic number of 122. Retains all the characteristics of an element. Central region is called the nucleus: consists of protons (positive charge) and neutrons (no electrical charge, electrons, negatively charged particles that surround the nucleus, located in discrete energy levels called shells.
