Fifth Element, The (1997)
IMDB rating: 7.20
Plot: Two hundred and fifty years in the future, life as we know it is threatened by the arrival of Evil. Only the fifth element (played by Milla Jovovich) can stop the Evil from extinguishing life, as it tries to do every five thousand years. She is helped by ex-soldier, current-cab-driver, Corben Dallas (played by Bruce Willis), who is, in turn, helped by Prince/Arsenio clone, Ruby Rhod. Unfortunately, Evil is being assisted by Mr. Zorg (Gary Oldman), who seeks to profit from the chaos that Evil will bring, and his alien mercenaries.

Help with AP chemistry.?
I was looking through an AP practice exam so I could practice for my final and these are the questions that I JUST DONT GET.
Would someone please help me?
1.Which of the following is a nonmetal in period 4?
a) C
b) Ca
c) Se
D) Sr
2. Predict which of the atom is most likely to be a metal
a) P
b) Br
c) As
d) Co
3. If x-rays have a shorter wavelength than ultraviolet-rays, which of the following statements is true?
a) x-rays have smaller frequencies than UV-rays.
b) X-rays travel faster than UV-rays
c) X-rays have more energy than UV-rays
d) X-rays have larger amplitudes than UV-rays
e) None of the above statements are true.
4. Arrange the following elements in order of increasing first ionization energy:
S, Ar, Ca.
a) S < Ar < Ca
b) Ca < Ar < S
c) S < Ca < Ar
d) Ca < S < Ar
5. What do we mean when we sat that "The energy of the electron in an atom is quantized?"
a) The electron has a very small amount of energy.
b) The energy of t he electron is proportional to the mass of the nucleus.
c) When an electron changes its energy, it emits a quantum of light.
d) The energy of the electron can have certain fixed energies and not others.
6. If the difference in electronegativity between two elements in a compound is very small (less than 0.2), can you safely conclude that the compound formed from the two elements is covalent?
a) Yes, because a small difference in electronegativity always indicates that a compound is covalent.
b) No, because covalent compounds are formed between two elements with a large difference in electronegativity.
c) Electronegativity has nothing to do with whether a bond is covalent or not.
d) No, because a metallic compound could also be formed between two elements with a small difference in electronegativity.
7. Which of the following relationships between the two variables listed for an ideal gas does NOT give a straight line graph with a positive slope?
a) P and T
b ) n and V
c) P and V
d) T and V
8. Samples of oxygen and helium have been collected in two separate containers of equal volume. Both gases have the same temperature and pressure.
a) The container of helium has the larger mass of gas.
b) The container of helium has the larger number of moles of gas.
c) Both containers have the same mass of gas.
d) Both containers have the same number of moles of gas.
9. Why does a hot air balloon rise when the air in the balloon is heated?
a) The average kinetic energy of the air molecules increases, and the collisions between these molecules and the walls of the balloon make it rise.
b) The pressure of the gas inside the balloon increases, pushing up the balloon.
c) The gas expands, forcing some of the gas to escape from the bottom of the balloon.
d) The balloon expands, causing it to rise.
10. X = CH3-CH2-CH2-CH2-CH3 Y = CH3-CH2-CH2-CH2-OH Z = HO-CH2-CH2-CH2-OH
Based on the concepts of polarity and hydrogen bonding, which of the following sequences correctly lists the compounds above in the order of their increasing solubility in water?

c) Temperature at which the solid, liquid, and vapor phases are all in equilibrium
d) Temperature at which liquid and vapor phases are in equilibrium at 1 atmosphere
e) Lowest temperature above which a substance cannot be liquefied at any applied pressure.

b) Electrons in atoms are arranged in shells.
c) Neutrons are at the center of an atom.
d) Neutrons and protons in atoms have nearly equal mass.
e) The Positive charge of an atom is concentrated in a small region.
