Argon

The symbol for argon is Ar. It is a colorless and odorless gas that makes up about 1% of Earth's atmosphere. Argon is often used in welding, lighting, and other industrial applications.

It is non-reactive because it's shells are full. Argon has three electron shells. It's third shell is filled with eight electrons. That is why it does not easily combine with other elements.

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.

Argon is a noble gas and exists as a monoatomic molecule in its natural state, which means it does not typically form ions. Its chemical symbol is Ar.

Formula: ArF3

But this compound does not exist

No, nitrogen and argon have different chemical properties. Nitrogen is a reactive diatomic nonmetal, while argon is a noble gas known for its inertness. Nitrogen tends to form compounds, while argon is largely unreactive.

Argon is a noble gas, which means it has a full outer electron shell, making it very stable and unreactive. It does not readily form chemical bonds with other elements because it already has a complete octet of electrons, making it energetically unfavorable to gain or lose electrons.

Argon is a noble gas, and thus it is not present in minerals. It is found in Earth's atmosphere in trace amounts and is also produced through the decay of radioactive materials.

To find the number of argon atoms in a 40.0-g sample, you first need to calculate the number of moles of argon in the sample using the molar mass of argon (39.95 g/mol). Then, you can use Avogadro's number (6.022x10^23 atoms/mol) to determine the number of atoms in that many moles of argon.

This tells us that argon has a full outer electron shell, making it stable and unreactive. Elements at the end of a period often have filled electron shells, giving them properties different from other elements in the same period.

Argon is the third most common gas in the Atmosphere, making up 0.934% of the atmosphere. On earth, Argon is only found in the atmosphere, because it is so inert it doesn't form compounds to inhabit the earth itself.

Argon is larger than neon because it has more electrons and a larger atomic radius.

Since the noble gases have completely filled orbital they usually do not take part in chemical reactions.So the major intermolecular forces in argon is the vanderwaal forces or London dispersion forces.

There are 4 protons in 9Be. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying Be-9) is unneeded.

Hard to say. It's a different price at every welding store, which is where you get things like argon.

Argon is sold in cylinders that hold a stated amount of gas, and the amount on the label is the number of cubic feet of this gas at STP. A popular size is 140 cubic feet, so we'll use that. (The cylinder is one-133rd that size in reality because they assume you are going to take your 140 cubic feet of gas at STP and compress it to 2000 psi. Acetylene tanks are different: because acetylene explodes at anything above 250 psi, they're calculated at that pressure. But this is a question about Ar, not C2H2.)

A mole of gas is 28.3 litres, or .79 cubic feet, at STP.

A mole of argon weighs 40 grams.

Therefore, 100 grams of argon is 1.975 cubic feet at STP. And there are 7088 grams of argon in a 140 cubic foot cylinder.

If we go to the welding store and find that exchanging a 140-cf cylinder of pure argon will cost $70.88 (it should be at least $20 cheaper, but this price makes the math easier), then by doing the math we will see that 100g of argon costs a dollar.

Liquid argon is also available, but almost all of it is sold to cylinder filling plants who warm it up and compress the resulting gaseous argon for sale to customers. There are a couple of scientific uses for liquid argon, but most people who need cryogenic temperatures use liquid nitrogen because it's less expensive and colder, or liquid helium because it's far colder.

Chemists store reactive chemicals in argon because it is an inert gas, meaning it is highly stable and does not react with most substances. By storing reactive chemicals in an inert atmosphere like argon, the risk of unintended chemical reactions, such as oxidation or hydrolysis, is minimized. This helps to preserve the chemical's stability and purity for future use.

Argon is a inert gas it cannot form argon triflouride

No, argon exists as a monatomic gas, meaning it is composed of individual argon atoms rather than diatomic molecules. Argon is a noble gas and is chemically inert, so it does not readily form bonds with other atoms or molecules.

When heat is applied to argon, the kinetic energy of the gas particles increases causing them to move faster and spread out further apart. Argon remains a gas at room temperature and pressure, so it will not undergo a phase change with moderate heating.

Argon is commonly used in welding to create an inert atmosphere that prevents oxidation of metals. It is also used in light bulbs to provide a stable and non-reactive environment for the filament to prolong its lifespan.

the equation is

Xg multiplied by the moles/grams of X = moles of X

(the grams cancel leaving you with moles)

607g Ar x 1 mole/ 39.95g = 15.19 moles

Mercury is the element used in fluorescent lights with argon. When electricity is passed through the mercury vapor inside the light tube, it produces ultraviolet light that excites the phosphor coating on the inside of the tube, creating visible light.

Argon is a noble gas and is generally considered non-toxic to humans. Inhaling argon in its pure form is not harmful as it is chemically inert and non-reactive. However, if argon displaces oxygen in an enclosed space, it can lead to asphyxiation due to oxygen deprivation.

If you look at the periodic table, Argon's atomic mass is forty, and its atomic number is eighteen. So forty minus eighteen = 22 neutrons
