100
The atomic nucleus is composed of these two particles.
What are protons and neutrons?
100
These are the units for molecular weight
What are grams per mole?
Or, with a slightly irritated look from the TA:
What are Atomic Mass Units?
100
This scale ranks the hardness of minerals, with soft minerals being 1, and very hard minerals being 10
What is the Moh's hardness scale?
100
This is the name of your TA.
Bonus 100 points: What is his email?

Bonus: wnelson@hawaii.edu
200
This element has 79 protons
What is gold?
200
Atoms that have lost or gained electrons are called this
What are ions?
200
This is how many items in a mole
What is avagadro's number?
Or what is 6.022*1023 atoms per mole?
200
This mineral is clear, scratches glass, and exhibits conchoidal fracture
What is quartz?
200
This many radians are in 180 degrees?
What are pi radians?
300
After oxygen, this is the most abundant element in the crust of the Earth.
What is Silicon?
300
The quantity of these particles determines an element's atomic number?
What are protons?
300
This is the molecular weight of CaCO3 (can be approximate) in g/mol
BONUS 100 points: What is the name of this mineral?
What is around 100 g/mol?
Ca= 40.08
C = 12.01
O = 16 (*3) = 48
= 100.06
Bonus: Calcite
300
This mineral is often clear, you can scratch with your fingernail, and has a white streak.
What is gypsum?
300
This is what you are testing for when you spray a rock with acid.
What is calcite?
Secret bonus 100: What are carbonates?
400
Elements who share this location on the periodic table tend to have the same properties.
Choose from:
period or group
partial credit (300 points) choose from:
Row or column
What is a group?
Partial:
What is a column?
400
These particles determine the bonding characteristics of an atom, and lie in the outermost layer of the electron cloud?
What are valence electrons?
400
These are the three types of bonds that involve valence electrons, and their characteristics.
What are ionic bonds (transfer of electrons), covalent bonds (sharing electrons), and Metallic bonds (sharing electrons which are allowed to move freely)?
400
Suppose homework is worth 20% of your grade, quizzes are worth 30% of your grade, and exams are worth 50% of your grade.
This is your grade if you scored and average of 74% on homework, 95% on quizzes, and 81% on exams.
What is 83.8%?
.2*74+.3*95+.5*81=83.8
500
These two elements tend to lose electrons to become ions having 2+ valence state.
Choose from:
Ca, K, Mg, Na
What are Ca and Mg?
These two elements are in the same column (or group)
Both have 2 electrons in their outer subshell, making them prone to electron donation.
500
This element has the complete electron configuration:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3
What is arsenic (As)?
500
This is the mass (in grams) of one mole of carbon atoms
Extra info:
Carbon has an atomic mass of about 12 g/mol
Avagadro's number= 6.022*2023
Plank's constant= 6.626*10-34 m^2 kg/s
What is 12 grams?
12 g/mol *1 mol= 12 g
500
This is how sunglasses dim light passing through them.
Bonus -100 points: "What is making the light darker?"
Bonus 100 points: Describe how this works (briefly)
What is polarization?
Bonus: Sunglasses basically filter out light with E fields oscillating in all directions but one, preserving the whole image, but reducing the overall intensity of the light going through them.
Or anything that basically presents this idea:
