Document Summary
10/11 current events: 66myo skull of triceratops (thornton, co) north of denver. Atoms -> minerals -> rocks -> weathering ->soils. Atom: built of protons (+), neutrons (no charge), and electrons (-) # of proton in nucleus determines what chemical element it is = atomic number. Ions = atom with a charge seeks stability, wants to be filled. 1. ionic boding = positive and negative ions that transfer an electron (important in minerals) (strong) 2. covalent bonding = produces strong and heart bonds (diamonds and water). 3. metallic bonding = shared among atoms, but very loosely held. Electron moves through quickly and easily. (bond with itself, gold, silver, copper, mercury) Complex ion strongly covalent bonded ions act like a single ion. Protons, neutrons, electron, cluster to form = atom. Elements (w/charge, ions & complex ions) bond to form covalent ionic bon mostly. Low temp: chemically (aragonite mud, ooids, dolomite, biologically (corals, molluscs) High temp: cooling from melt (olivine, feldspar, quartz (most minerals form.
