How many atoms does a molecule of astatine vapor contain?
Most likely it would be two.
What of an element is determined experimentally by bombardment of atoms in the vapor phase with a stream of electrons?
The answer that you wish to acquire is ionization energy. pretty sure at least. ;)
What kind of bond in AlCl3 have?
AlCl3 at high temperatres in the vapor phase is molcular, planar AlCl3. with polar covalent bonds. In the melt and at lower temperatures in the vapor phase it is dimeric, Al2Cl6 with two bridging Cl atoms ( Cl2AlCl2AlCl2), each aluminium atom is approximately surrounded by a tetrahedron of Cl atoms. in the solid the structure has each Al surrounded by 6 Cl atoms and the bonding is more ionic in nature. As the solid is heated just before it melts the electrical conductivity rises due to the presence of ions.
Are the only gases the diatomic gases and the noble gases?
No - there are many gases that contain more than one or two atoms. Some examples are: Carbon Dioxide: 3 atoms Acetylene: 4 atoms Methane: 5 atoms Ethylene: 6 atoms . . . and the list goes on. It is true though that as the more atoms a molecule consists of, the less likely it is to be a gas at a temperature we are familiar with. Pretty nearly all molecules can be gases if the pressure is low enough and the temperature is high enough (unless they decompose before they can be heated enough to make their vapor pressure exceed the ambient pressure).
What form of water is the most abundant at any time in the water cycle?
water vapor

Is air a vapor?
Oxygen is made up of an acid and a base hydrogen and hydronium atoms
Why does water vapour have less density than dry air?
First you must understand "density." Density is the amount of atoms in a given volume. You can artificially create situations when there are more atoms in a given volume where the atoms are either "dry air" or "water vapor." But in ordinary situations, water vapor is mixed with what we call "air" and in ordinary situations, "dry air" has less water vapor in a given volume, so, people tend to say that water vapor is "heavy" or more "dense" than "air" or "dry air."
What is the relationship between temperature air molecules and water vapor?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
What is the relationship between water vapor air molecules temperature?

That Na and Hg in vapour state exist as monoatomic molecules?
that would make it the gaseous atoms if they are exist in "monoatomic"molecules and the answer is yes.mercury vapor and sodium vapor lightening depend upon that fact
How many atoms are in 131.97 liters of water vapor at STP?
Use the ideal gas equation to get moles of water vapor. PV = nRT (1 atm)(131.97 L) = n(0.08206 L*atm/mol*K)(298.15 K) = 5.3939 moles H2O (6.022 X 10^23/1 mole H2O) = 3.2482 X 10^24 atoms of water vapor --------------------------------------------------------
Is water vapor a form of crystals?
No, crystallization requires a solid material of atoms or ions that arrange in an orderly repeating pattern in all three dimensions. Water vapor is merely the gas state of H20.
Why gas can't be seen?
Some gasses can be seen (e.g. chlorine, fluorine, iodine vapor) and some cannot be seen (e.g. nitrogen, helium, water vapor). It depends on how light interacts with the atoms.
Does a cold object have more or less atoms?
same number of atoms theoretically... yet cold objects collect water vapor cold objects shrink and hot objects expand with the exception of water.

Is mercury's vapor pressure low?
because it is evaporated as atom i.e the interaction between atoms is high so high energy needed to evaporate Hg
