GLY 1010 Study Guide - Midterm Guide: Silicate Minerals, Subatomic Particle, Covalent Bond
Document Summary
The smallest particle that exists as an element. Two or more minerals having the same chemical composition but different crystalline structures. Exemplified by the diamond and graphite forms of carbon. Any break or rupture in rock along which no appreciable movement has taken place. Silicate minerals containing ions of iron and/or magnesium in their structure. They are dark color and have a higher specific gravity than nonferromagnesian silicates. A chemical bond produced by the sharing of electrons. A subatomic particle found in the nucleus of an atom. The neutron is electrically neutral, with a mass approximately equal to that of a proton. They are generally lighter in color and have lower specific gravities than dark silicates. The electrons involved in the bonding process; the electrons occupying the highest principal energy level of an atom. The sum of number of neutrons and protons in the nucleus of an atom.
