Geology 100 Professor Ohan Chapter 3 1) A mineral is any naturally occurring inorganic solid that possesses an orderly crystalline structure and a well defined chemical composition. Most rocks are aggregates composed of two or more minerals. 2) The building blocks of minerals are elements. An atom is the smallest particle of matter that still retains the characteristics of an element. Each atom has a nucleus, which contains protons (partials with positive electrical charges) and neutrons (partials with neutral electrical charges). 3) Orbiting the nucleus of an atom in regions called energy levels, or principal shells, are electrons, which have negative electrical charges. The number of protons in an atom’s nucleuses determines its atomic number and the name of the element. 4) Atoms combine with each other to form more complex substances called compounds. Atoms bond together by gaining, losing, or sharing electrons with other atoms. In ionic bonding, one or more electrons are transferred from one atom to another, giving the atoms a net positive or negative charge. 5) The resulting electrically charged atoms are called ions assembled in a regular, crystalline structure that allows for the maximum attraction ions, given their sizes. Another type of bond, the covalent bond, is produced when atoms share electrons. 6)
