It is very commonly said that argon lacks a smell of any kind, and is non-toxic.


Is argon monatomic?


Periodic Table

What is the element argon named after?

Argon comes from the similarly-pronounced greek word "αργος," meaning 'inactive' or 'lazy', referring to Argon's inert nature.

Argon, like other noble gases, has a full P-Shell of valence electrons, meaning it doesn't need to lose or gain any electrons to complete the shell, making it incredibly stable in an elemental state. This is what makes the noble gases inert, there is no benefit to them forming compounds, so they don't. In fact the formation of a compound would mean to give up having a full P-Shell and so is very unfavourable. Very few noble gas-containing compounds exist.

This doesn't mean they are useless, however. Inert gases are highly useful for running oxygen-sensitive reactions under. In a lab I would use a Schlenk line for running such reactions, we usually fill this with Nitrogen gas (N2) but often Argon is a more suitable alternative. It is also used for high-temperature applications (which helps Argon react) and in fluorescent lighting.

What would happen if you drank some rubbing alcohol?

Before you died, you would be permanently blinded.

It's a very, very, very bad idea.

AnswerWe just had a 9th grade student do this - about a styrofoam cup full. The state poison control center said that this amount would not cause lethal damage but could cause some upset stomach (it did) and some intoxication effects. He did NOT mention blindness or death as possibilities, although if it were an ongoing thing of daily drinking it would likely be more of a problem.

if it was only a small dose you will be fine but have a terrible time trying to sleep


Why does argon not form ions?

Atoms become ions by gaining or losing electrons to achieve a noble gas configuration of electrons, which is stable.

Argon already has such a configuration and is very stable as it is. Any gain or loss of electrons would make it less stable.

What are some uses for argon?

TroyFills light bulbs and incandescent lamps to protect the filament.

Used in fluorescent tubes, glow tubes, etc. Usually emits blue light.

Forms inert atmosphere that's good for many forms of welding.

Extinguishes fires without damaging sex toys As a protective atmosphere for growing silicon and germanium crystals.

Used in museums to protect and preserve old documents or materials.

Keeps open bottles of wine from oxidizing and to top off wine barrels, so the wine doesn't turn into vinegar during the aging process.

Used in thermal insulation of energy-efficient windows because of its low thermal conductivity.

Used in technical scuba diving to inflate dry suits

Argon lasers are used in surgery to weld arteries, destroy tumors, or correct eye defects.

Some forms of argon are used in dating ground water, igneous rocks, and ice cores.


How many neutrons are in argon?

The number of neutrons is 22(for the most stable isotope of argon, Ar-40)

because you subtract the atomic mass from the atomic number then estimate!

The most common isotope of Argon, 40Ar, (comprising about 99.6% of all naturally occurring Argon) has 22 neutrons 18 electrons 18 protons.

Argon has 24 known isotopes ranging from 30Ar (with 12 neutrons) to 53Ar (with 35 neutrons).

Of those only three are stable: 36Ar, 38Ar, and 40Ar.

What are the limitations of carbon 14 for dating?

There are several limitations of carbon 14 dating. Firstly, carbon dating can only be used on objects that were or are living, meaning that man-made objects cannot be tested. Secondly, the sample tested must be quite large in size, because part of the object is broken down and lost when it is cleaned and distilled. The loss of the part may cause an inaccurate date given to the object. Thirdly, Changes in the atmosphere, particularly the thinning of the ozone, cause more Carbon 14 to be produced, so the standard measurement of the Carbon 14 existing in the time used to compare with the fossil must be transferred to the correct must be transferred to the correct amount, and these changes have not yet occurred.
Carbon dating is only effective at dating objects of up to 70,000 years in age


What are future uses for argon?

lasers, light bulbs, inert gases, liquids, liquid detectors


Which element had the largest atom potassium or argon?



What is the freezing point of saltwater?

The freezing point of salt water varies depending on how much salt is in the water. For example, water that is 3500 parts per million salt (avg. amount in seawater) will freeze around -2 degrees Celsius (28 degrees F). Water with an extreme amount of salt in it, like in some lake waters in Death Valley CA, with 300,000 ppm, will freeze at -20 to -30 degrees C (-4 to -20 degrees F).

The degree Fahrenheit (°F) is a unit of temperature named for the German physicist Gabriel Fahrenheit (1686 - 1736). In the Fahrenheit scale of temperature the freezing point of water is 32 degrees and the boiling point is 212 degrees, placing the boiling and melting points of water 180 degrees apart. Zero degrees Fahrenheit indicates the lowest temperature Fahrenheit could obtain by a mixture of ice and salt.
That depends on a number of factors including the concentration of salt in the water and the type of salt in the solution. Sodium Chloride (NaCl) can exist in aqueous (water-based) solutions with concentrations ranging from 0% to about 23% by weight. The maximum concentration, which corresponds to the saturation point for the solution, is dependent on temperature. The freezing point for a 23% NaCl solution is about -21 degrees C.

The salt that highway authorities apply to roadways depends on the expected minimum temperature. For roadway temperatures below -12 degrees C, authorities do not use Sodium Chloride but may use Calcium Chloride instead because it remains effective at lower temperatures.

The freezing temperature of seawater also depends on salinity (salt concentration) as well as pressure.

What is special about the outer electron orbits of helium neon and argon?



Why would an inert gas such as argon be called 'the lazy one'?

Because of its chemical inactivity

Atoms and Atomic Structure

What is an inert atom?

It an atom that is extremely unreactive. The most inert atoms are the noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr) and xenon (Xe). Their valence electron shells are complete (the so-called octet rule is satisfied).


What is the formula for argon and sodium?

Argon is ar and sodium is na.


What happens when you mix argon and hydrogen?

You just get a gas mixture of argon and hydrogen. Being less dense, the hydrogen will rise above the argon.

Elements and Compounds

What are the features of metals and non-metals?

AnswerFeatures of Metals: Metals are characterized by the lustrous shine they provide. They also conduct electricity, are electropositive in nature and react with mineral acids to liberate hydrogen. They are usually solid at 20 degrees celcius. They are usually brittle and hard, but those like sodium are waxy and can be cut with the help of a knife.

Features of non-metals: Non-metals may be solids, liquids or gases. They do not conduct electricity under normal conditions. They may be electropositive or electronegative in nature. If solids, they are usually powdery or lumps without luster.

Why is Freddy lighter than Jason?

Because Freddy is an old man, and Jason is a hulking teenager who probably would have played on the football team if people weren't such jerks.

AnswerBecause parents of the kids, he killed made him burn some fat.


Because Freddy doesn't lift the fork to his mouth every 15 seconds.


because Freddy doesnt have a butter knife for an arm

My answer:

because Jason is a HUGE guy, he is massive, wheras freddy is an average size person, because freddies power doesnt come from strength, it comes from using peoples minds to kill them.

Is nitrogen lighter than air?

If you are asking whether nitrogen is less dense than air and will float on top of it, then yes, nitrogen is "lighter," albeit only slightly. More accurately, nitrogen, which is a constituent gas of air, is less dense than air, not lighter. The density of air at standard temperature and pressure is 1.292 kg/m3. The density of nitrogen is 1.251 kg/m3.
