🗑
|
||||
| Isotape | All isotapes have the same # of protons, different number of neutrons
🗑
|
||||
| Shell model of the atom | at least 7 shells; each shell can hold a limited number of electrons; inner holds 2; 2nd & 3rd holds 8 each; 4th and 5th holds 18 each, and 6th and 7th holds 32 each
🗑
|
||||
| Valance electrons | Electrons in the outer shell; they are available to participate in chemical bonding
🗑
|
||||
| Determining the valance electrons using the periodic table | groups, the columns
🗑
|
||||
| Covalent bonds | sharing of electron pairs; same element oe close to each other in the periodic table; primarily between non-metals
🗑
|
||||
| Ionic bonds | electrostatic force of attraction between two oppositely charged ions (cation) and the negative ion (anion); one electron donor and one electron acceptor (seesaw)
🗑
|
||||
| organic compound | Molecules associated with living organisms; any compound containing a carbon atom
🗑
|
||||
| inorganic compound | Non living; any compound lacking carbon atoms
🗑
|
||||
| Hydrocarbon | organic compound consisting entirely of H and C
🗑
|
||||
| Pure substance | consists of only one type of atom, molecule, or ion e.g. tin, water, table salt
🗑
|
||||
| Mixture | collection of two or more atoms, molecules or ions that are physically mixed
🗑
|
||||
| Heterogeneous mixture | contains substances that are not evenly distributed e.g. bowl of cereal, pizza
🗑
|
||||
| Homogeneous mixture | substances are evenly distributed e.g. honey, air
🗑
|
||||
| Solution | homogeneous mixture consisting of ions or molecules e.g. vodka, salt water, sugar water
🗑
|
||||
| Solids | occupy a constant amount of space and does not readily deform
🗑
|
||||
| Liquids | occupy space; form changes readily
🗑
|
||||
| Gas | has neither volume nor shape; assumes shape/volume of the container
🗑
|
||||
| When an arrangement melts | molecules begin to move around more and more; they spread out
🗑
|
||||
| When an arrangement freezes | molecules slow down and become more compact
🗑
|
||||
| Addition of heat energy; Boiling causes | molecules move/vibrate quickly; they separate and create gas
🗑
|
||||
| Conductor materials | electric current can flow freely; outer electrons are loosely bound and move freely through material
🗑
|
||||
| Insulators | prevent the flow of electrons; outer electrons tightly bound
🗑
|
||||
| Metals | solid at room temp; has a density of 19.3 grams per milliliter e.g. gold, zinc, sodium
🗑
|
||||
| Nonmetals | solid at room temp; has a density of 3.5 grams per milliliter e.g. oxygen, carbon
🗑
|
||||
| Metalloids | silicon, arsenic
🗑
|
||||
| Minerals | rocks and inorganic materially; naturally ocurring
🗑
|
||||
| Silicates | most common mineral group; contains oxygen and silica; 95% of Earths surface crust e.g. quartz, talc, garnet
🗑
|
||||
| Non-silicates | usually not rock forming minerals; no silicates e.g. calcite, dolomite, gypsum, alabaster, copper, silver, gold
🗑
|
||||
| Igneous rocks | crystalline solids for directly for the cooling of magna; names represent composition and texture e.g. granite, lava, pumice
🗑
|
||||
| Metamorphic rocks | "meta" (change) "morph" (form) any rock can become this; e.g. slate, schist, gneiss, marble
🗑
|
||||
| Sedimentary rocks | they are secondary rock; they are the result of accumulation of small pieces broken off of pre-existing rocks e.g. conglomerate, limestone, dolomite, travertine, shale
🗑
|
||||
| Seismic waves | waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs.
🗑
|
||||
| P-waves | primary waves; fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station; can move through solid rock and fluids, like water or the liquid layers of the earth
🗑
|
||||
| S-waves | secondary waves; which is the second wave you feel in an earthquake; can only move through solid rock, not through any liquid medium.
🗑
|
||||
| Composition of earth | inner core, outer core, mantle, crust
🗑
|
||||
| Inner core | solid iron and nickel, dense
🗑
|
||||
| Outer core | liquid; mostly iron

🗑
|
||||
| Happens in the outer core when the earth spins | creates a magnetic field by moving electrical current
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
