Argon (Ar) is an element.
It is found in Group 0 of the Periodic Table (usually the column furthest to the right), which is the group for noble gases. They are very unreactive, so are unlikely to form compounds.
It's an element. It has atomic number 18 with symbol Ar. It is a noble gas. For more information, see the Web Links to the left of this answer.
Argon, like all elements, is a pure substance.
Argon is not a compound at all.
It is an element. Specifically it is a noble gas.
Argon is one of the noble gases.
pure element
Neither. Argon is a gas.
no, argon is an element.

Gas in atmosphere: argon Liquid in atmosphere: water (as rain) Solid in atmosphere: dust
It can be a solid liquid or a gas, depending on the temperature
solid liquid
Mud is a solid not a liquid if you wanted to know :]
Liquid to solid is a phase change.
Solid Argon is more dense than the liquid phase
Argon is a gas at STP. It becomes a liquid below -186oC and solid below -190oC at StP
Argon is a gas at STP. It becomes a liquid below -186oC and solid below -190oC at StP
Argon is a gas at room temperatures.
Matter has more density when solid than when in a liquid state. The atoms are closer together.

It can be a solid liquid or a gas, depending on the temperature
This depends on temperature and pressure, consider h2o. Is "water" a solid liquid or gas? Clouds are water vapor as is steam, rivers oceans and lakes are liquid, and icebergs are solids. However, Argon is a gas in earths atmosphere so at those conditions it is a gas. Argon is solid at temperatures below -189.3°C, at which temperature it liquefies. It is a gas at temperatures of -185.86°C and higher.
Willem van Witzenburg has written: 'The equation of state of liquid and solid argon' -- subject(s): Argon
i think argon is solid
Argon can be transformed in to a liquid. Argon changes from a gas to a liquid at -185.86°C (-302.55°F).
