Lecture 3 - Minerals 29/01/2008 09:15:00 Mineral definition: A naturally occurring inorganic solid with a regular internal  atomic structure and a specific chemical composition. Mineral Atomic Structure o Minerals are made of atoms, atom is smallest object.  Atoms consist of  nucleus blah blah blah o Atomic # = # of Protons o Hydrogen: 1P, Helium: 2P, Carbon: 6P o Atomic mass = Protons + Neutrons o Lots of Carbon-12, 98.9% is carbon-12, 1.1% is carbon-13 o and unstable, will break apart o Bonding Ionic Bond – Electron transfer, most common is salt, NaCl. Na  has 2-8-1 and Cl has 2-8-7, Na loses one becoming negative  and Cl gains one becoming positive and they become attracted. Covalent – Electron sharing, generally strongest. Van Der Waals Bond – Sides of atoms become a little unevenly
