26. Nonmetallic elements are more likely to lose electrons.
27. Noble Gases are nonreactive and extremely stable.
28.
a. cation
b. cation
c. anion
d. cation
e. anion
f. cation
g. cation
h. anion
29. Copper metal and copper ions differ because two
electrons are absent. It is a much larger change when neutrons alter as opposed
to when electrons alter because of the size difference.
30. 156 + 254= 410
410
/ 10= 205
31.
a. Chemical: rusting which changes the color due to oxygen
change
Physical: painting something in order to change its color
b. Chemical: combustion to heat up
Physical: boiling/ freezing point
c. Chemical: reaction with acid
Physical: water vapor that rises after boiling
32.
a. Bromine
b. Silicon
33. Mendeleev used atomic weight along with similarities in
chemical and physical properties to organize the periodic table. In analyzing
our Snake River data to solve the fish-kill mystery in Unit 1, we had to
compare mass changes among the different substances we tested for with the
normal masses. We used our knowledge of properties of the different substances
to create legitimate and logical hypotheses
34. Argon (atomic weight: 39.95) would have had to be placed
after potassium (atomic weight: 39.10), and cobalt (atomic weight: 58.93) would
have had to be placed after nickel (58.69) in order to be accurate in
Mendeleev's original periodic table
2SBS:
1)
Atmosphere: nitrogen, oxygen, neon, argon
Hydrosphere: water, dissolved minerals
Lithosphere: petroleum, metal-bearing ores
2)
a. The crust= the thin band of soil and rock containing major raw materials needed to build all manufactured objects.
-The mantle= the middle layer of the lithosphere.
-The core= Earth's center: extremely hot.
b. The crust is the main storehouse of chemical resources

3)
a. Mexico
b. Japan
c. China
4)
China produces the largest mass of the eight resources on the table.
5)
Ores are naturally occurring rocks or minerals that can be mined and from which are profitable to extract a metal or other metal. Minerals are naturally occurring solid compounds containing the element or group of elements of interest.
6)
-the quantity of useful ore found at the site.
-the percent of metal in the ore.
-the type of mining and processing needed to extract the metal from its ore.
-the environmental impact of the mining and metal processing.
7)
It is possible that the gold had replaced after 100 years and demand for gold was high.
8)
Useful ore refers to the amount of the desired mineral being minded.
