The boiling point of aluminium is 2 470 0C.
all atoms are generally the same size, so "large atoms" would mean molecules.
Typically, the gas would be the solute and the liquid would be the solvent. But it really depends on what is present in the largest amount. The phase present in the largest volume is the solvent; the other is the solute.
Nonexistite. Such a compound would not be stable, unless there are additional atoms you're not telling us about. Aluminium (III) oxide, aka aluminum oxide, alumina, or corundum, would be Al2O3.
The Sun is not a planet. It is a star. The Earth has gas on it, but it is not gaseous compared to the planets defined as gaseous. So your answer would be no the Sun and the Earth are not gaseous planets.
I would say the noble gases since as gases their atoms are isolated and they do not form diatomic molecules like all the other gaseous elements.
The formula would be AlCl3, which is aluminum chloride.
It decreases. In gaseous phase the molecules are further apart than they are in the solid phase so although in solid phase the molecules are still moving minimally they haven't got the space to move around in that they would in the gaseous phase.

Gaseous. If that is 150 degrees C, that would be steam.
that would depend on the type of atoms and your definition of metallic.
Which of the billions of possible equations that contain aluminum are you asking about?
Not at all. Aluminum oxide is a compound of aluminum, not an allotrope. An allotrope of aluminum would still be called aluminum, but sometimes we distinguish allotropes by assigning numbers, such as sulfur-1, sulfur-2, etc. It refers to the specific structure which the atoms form (such as crystaline vs. amorphous).
Roughly 1,000,000
Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1 meaning you need 3 chlorine for every 1 Aluminum to cancel the charges.Because of the chlorine, it would most likely be aqueous, or dissolved in a liquid.
Typically, the gas would be the solute and the liquid would be the solvent. But it really depends on what is present in the largest amount. The phase present in the largest volume is the solvent; the other is the solute.
No, remember any element heated to a high enough temperature will form a gaseous phase for instance mercury vapour would be heavier than H2S.
The phase of matter that has the least kinetic energy is the solid phase. You know that temperature is a measure of kinetic energy among molecules of a substance and solid is the phase of matter that occurs at the lowest temperature.
