1 Time to see your advisor Registration November

2 5 points Extra Credit Seminar this week in NS 103 Wednesday November 11, noon to 1 Attend, write a ½ to 1 page content and reflection paper p describing the presentation and how it relates to our environment, this class, your life, etc. Due by Noon Friday November 13 by attachment to brownk@wou.edu, or handwritten in your next lecture class after the seminar (Nov 11 or 12)

3 MINERALS

4 Mineral Naturally occurring Inorganic Solid Regularly repeating internal arrangement of atoms Definite chemical composition Rocks may be composed of minerals and/or other material

5 Periodic table

6 Atomic structure

7 ATOM FEATURES Nucleus contains both protons and neutrons Each atom of an element has the same number of protons in the nucleus Different atoms of the same element may have different numbers of neutrons in the nucleus These differing-neutron neutron atoms are called isotopes

8 Shells of electrons

9 ELECTRON FEATURES Electrons occur in a cloud around nucleus More likely to occur at certain distances and with a certain amount of energy than in other places the energy shells Inner shells fill before outer shells are created Full shells more stable than partial shells

10 PERIODIC TABLE Arranged from lowest atomic number to highest, h from left to right, from top to bottom Each row corresponds to an energy level (electron shell) Each column contains elements e e with similar properties, which repeat on a regular (or periodic) basiss These similar properties are a result of the same number of electrons in the outermost shell

11 Periodic table

12 Ionic bonding Result of stability of filled outer shells of electrons Sodium apt to lose its lone outer electron Chlorine apt to fill its nearly-full outer shell

13 Nucleus of atom 1. All except Contains the electrons 3. Contains the neutrons 4. Contains the protons 5. Is responsible for most of the mass of the atom 0% 0% 0% 0% 0%

14 Electrons 1. All of these 2. Are a function of the periodic table 3. Are very low mass compared to protons and neutrons 4. Don t participate in atomic bonding 5. Have a neutral charge 0% 0% 0% 0% 0%

15 Mineral 1. All of these 2. Dietary supplement 3. Made of rock 4. Natural crystalline compound 5. Same as element 0% 0% 0% 0% 0%

16 Elemental Abundance in Crust

17 Silica tetrahedron

18 Isolated and chain Silicate Structure

19 Olivine crystal

20 Hornblende

21 Sheet silicate structure

22 Cleavage mica

23 Framework silicate structure

24 Potassium Feldspar

25 Quartz: conchoidal and irregular fracture 1IgneousMineralz/Quartz.html

26 IMPORTANT MINERAL PROPERTIES LUSTER: all minerals have it CRYSTAL FORM: some show it STREAK: color oo may aybe white COLOR: may be diagnostic

27 Quartz crystals

28 Pyrite crystals

29 Pyritohedrons Five sided faces Ten faces Often striated

30 Hornblende

31 Fluorite crystals

32 streak

33 Color may not help to identify mineral These are all quartz 1IgneousMineralz/Quartz.html

34 Color may not help to identify mineral _v1.htm orado/mineral_rhodochrosite.html

35 Color may be diagnostic

36 Copper

37 Nonsilicate bornite copper ore

38 IMPORTANT MINERAL PROPERTIES HARDNESS: compare to common items CLEAVAGE: planes of internal weakness FRACTURE SPECIFIC GRAVITY: density, heft OTHER PROPERTIES MAGNETISM, TASTE, SMELL FIZZ IN Hydrochloric ACID DILUTE, HEATED, IF MINERAL IS POWDERED DOUBLE REFRACTION

39 Hardness 1 Tl 6. Orthoclase 1. Talc 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 7. Quartz Fingernail 2.5 Streak plate 7.5 Penny 3.5 Steel nail 5 Glass Topaz 9. Corundum 10. Diamond

40 Conchoidal fracture quartz

41 Cleavage muscovite

42 Potassium Feldspar

43 Plagioclase

44 Hornblende

45 Galena cleavage

46 Halite

47 Calcite

48 Fibrous fracture asbesoform mineral

49 Effervescence

50 Double Refraction

51 The resistance of a mineral to abrasion is known as. 1. cleavage 2. luster 3. Hardness 4. None of these 5. streak 0% 0% 0% 0% 0%

52 What element is the most abundant in Earth s crust by weight? 1. carbon 2. chlorine 3. Oxygen 4. silicon 5. sodium 0% 0% 0% 0% 0%

53 Which of the following has the highest specific gravity? 1. gold 2. ice 3. Quartz 4. water 5. wood 0% 0% 0% 0% 0%

54 The strong tendency of certain minerals to break along smooth, parallel planes is known as. 1. cleavage 2. cracking luster 3. fracture 4. habit 5. streak 0% 0% 0% 0% 0%

55 The most unreliable (variable) diagnostic property of minerals such as quartz is. 1. color 2. habit 3. hardness 4. specific gravity 5. streak 0% 0% 0% 0% 0%

56 Input the 1st of six number of your v # with the transmitters (after the V00 part) V Enter this digit now as soon as the polling box turns green and says open I will ask for the second digit shortly Do not press the number for the second digit until I ask for it with the next slide If you make a mistake, reenter the proper number before we go on to the next slide Do not push the GO button unless you need to recode it transmit frequency!! ( when you push GO it resets the frequency it transmit on)

57 Now input the 2nd number after the V00 with the transmitters V this digit only, not any others when the polling box turns green! If you make a mistake, reenter the proper number before we go on to the next slide Do not push the GO button!!

58 It s time to input the 3rd number with the transmitters V This digit only Do not go on to the next digit until I go to the next slide!! If you make a mistake, reenter the proper number before we go on to the next slide If you didn t get an entry, enter the proper one for this slide, not the one for the previous slide

59 We are up to the 4th digit of your V# V If you make a mistake, reenter the proper number before we go on to the next slide If you didn t get an entry, enter the proper one for this slide, not the one for the previous slide Do not push the GO button!!

60 Input the 5th digit now V Do not go on to the next digit until I go to the next slide If you make a mistake, reenter the proper p number If you didn t get an entry, enter the proper one for this slide, not the one for the previous slide Do not push the GO button!!

61 Input the LAST DIGIT of your v # with the clickers V when the polling box turns green If you make a mistake, reenter the proper number Do not push the GO button!!
