What are valence electrons and how do you figure out how many an atom has?
Valence electrons are the electrons that orbit in the outer most orbital/shell. They are determined by the group number in the periodic table.

How many electrons does a positive ion of Aluminum with a +2 charge have?
+2 Aluminum = 13 +protons and 11 -electrons

When hot air is blown into a hot-air-balloon, it begins to rise in the atmosphere.
Explain how density, temperature, and air particle movement explains this phenomena.
When the hot air inside the balloon is hotter than the air outside, the particles begin to move faster which increases the volume of the balloon, making it less dense than the air around it. Things that are less dense (balloon) float above things that are more dense (air around balloon).
