Argon

The outgassings of the Earth was stripped away by solar winds early in the history of the planet until a steady state was established, the first atmosphere. Based on today's volcanic evidence, this atmosphere would have contained 80% water vapor, 10% carbon dioxide, 5 to 7% hydrogen-sulfur, and smaller amounts of nitrogen, carbon monoxide, hydrogen, methane and inert gases.

It can be a solid liquid or a gas, depending on the temperature

Argon does occur in potassium-containing minerals as a result of the radioactive decay of K-40. However, this is not a significant source commercially; at nearly 1%, argon is the third most abundant component of the Earth's atmosphere, and it's extracted via fractional distillation of liquefied air.

Because the trend is the same. Atomic radius decreases from left to right across a period.

"filled with nothing" ???

yes is the answer your looking for, but the bulbs we use today are optimized to work with whatever gases each company uses.

Oxygen is the destroyer of fillaments (remember the old flash bulbs?)

You probably could fill it, but not to pressures needed for paintball gun operation, CO2 tanks should not be filled with any gas or liquid besides CO2.

edit: you could use Argon in a HPA tank but not a CO2 tank

Hydrogen is unique in that it's atoms have a single proton, and typically, a single electron.

When hydrogen undergoes a reaction with a metal, it will gain another electron. This makes two in its only energy level, which is therefore its valence shell as well. Hydrogen (an exception to the octet rule) is satisfied with only two electrons in its valence shell, and acts like a non-metal in this fashion.

Alternatively, hydrogen can also lose it's only electron. This happens, usually, when it reacts with a non-metal. In this case, hydrogen is acting like a metal by giving up it's electron.

Argon is better. Helium can't compare to it, not in terms of cost, usefullness,

availability, personality, attractive appearance, intelligence, or ambition.

One more electron.

Xenon and argon are the elements used in fluorescent lights.

Helium

First check with post office on regulations, possibly need to have second address IE; 1990 and 19901/2 if same, but first check postal regulations and codes.

No. Argon is slightly denser than air so would not be collected by upward delivery. In practice downward delivery would be unreliable as the difference in density is so small. However there is no way to prepare argon in the lab so the question is redundant.

Argon does not readily form stable compounds under normal conditions, including argon oxide.

Argon is a non metal element. Mass number of it is 40.

To find the number of argon atoms, we first need to determine the molar mass of argon: 39.95 g/mol. Next, we convert the given mass to moles using the molar mass: 1.5 x 10^2 g / 39.95 g/mol = 3.75 mol. Finally, we use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms: 3.75 mol x 6.022 x 10^23 atoms/mol ≈ 2.26 x 10^24 argon atoms.

When neon, argon, and helium are combined, they form a mixture of noble gases. These gases are colorless, odorless, and generally inert. The resulting mixture would not undergo any chemical reactions with each other.

When oxygen reacts with argon, it forms argon oxide compounds such as argon(II) oxide (ArO) or argon(IV) oxide (ArO2). These compounds are unstable and tend to decompose easily. This reaction is not commonly observed under normal conditions as argon is generally inert and does not readily react with other elements.

Chemists store reactive chemicals in argon to prevent oxidation or reaction with oxygen and moisture in the air. Argon is an inert gas that does not react with most chemicals, providing a stable and oxygen-free environment for storing sensitive compounds. This helps to maintain the purity and stability of the chemicals for future use.

Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.

Argon makes up about 0.93% of Earth's atmosphere, including inhaled air. However, because argon is chemically inert and does not take part in the body's metabolic processes, it is exhaled in the same concentration as it was inhaled.

There is no argon oil.

It can be used for that purpose.

Argon is a monatomic noble gas. It has 8 electrons in its outermost energy level, making it chemically inert. Its usefulness stems from the fact that it is so unreactive: it is used as an atmosphere to protect things from reaction with the air, e.g, during welding and in the production of titanium. It is used to fill light bulbs, and in strip lights. It is slightly denser than air.
