Noble Gases

Compressed helium does not lift more than regular helium. The lifting force generated by a gas is determined by its density, regardless of whether it is compressed or not. Helium is already a very low-density gas, so compressing it would not significantly increase its lifting capacity.

Yes, liquid helium boiling is a physical property. Boiling point is a physical property that describes the temperature at which a substance changes from a liquid to a gas. In the case of helium, its boiling point is very low at -268.9 degrees Celsius.

Helium doesnot have a gender. It is a chemical element

Noble gases are unique because they have a full outer electron shell, making them stable and non-reactive. This stable electron configuration means they rarely form compounds with other elements. In contrast, most other elements tend to form compounds by either losing, gaining, or sharing electrons to achieve a full outer shell.

A neutral atom of helium must possess two electrons. Each electron carries a negative charge of -1, and since helium has a charge of 0 (neutral), the number of electrons must equal the number of protons, which is 2 in the case of helium.

Helium, Neon, Argon and if another Krypton.

The Earth has a radius of 6,360 km. The crust varies in thickness from around 5-70 km with an average value of around 35 km.

As such Earth's crust is between approximately 0.07 and 1.1 % of the total thickness of the Earth (average of 0.55 %).

I thought I heard 1% on radio, but would like to see a real citation.

Argon is a noble gas that is less dense than air, which causes it to be buoyant and float when released into the atmosphere. This is due to the fact that the average atomic mass of argon is lower than the average molecular weight of air, leading to its upward movement.

Yes, Party City typically offers helium tank refills in-store for a fee. Customers can bring in their empty tanks and exchange them for refilled ones. It's best to contact your local Party City store for specifics on their helium tank refill services.

helium is in row 1 (or better period 1)

Inert gases themselves do not explode because they are chemically stable and non-reactive. However, when mixed with a flammable substance in the presence of an ignition source, they can contribute to explosion hazards by displacing oxygen and creating a flammable atmosphere.

Because it has 8 valence electrons (completely filled orbitals) as do other noble gases.

No, sodium is not a noble gas. It is a reactive metal that belongs to the alkali metal group in the periodic table. Noble gases are a group of non-reactive elements that include helium, neon, argon, krypton, xenon, and radon.

Noble gases have complete outer electron shells, making them stable and unreactive. This stability arises from their full valence shell configuration, which means they do not readily gain, lose, or share electrons with other atoms.

The symbol of helium is he

The radical of helium is He·. Helium does not naturally form radicals in the same way that other elements do, but in certain conditions it can form a radical by gaining an extra electron to become negatively charged.

Helium does not burn because it is an inert gas, meaning it does not undergo chemical reactions like combustion.

Zinc is not a noble gas because noble gases have a full outer electron shell, while zinc only has a full 3d orbital. Noble gases have a stable electron configuration with the maximum number of electrons in their outer shell, making them chemically inert, which is not the case for zinc.

Yes, Boyle's Law is applicable to noble gases. Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. This relationship holds true for all gases, including noble gases like helium, neon, and argon.

Noble gases have electronegativity values of zero because they have completed the fulfillment of their orbitals and are no longer looking to bond with anymore electrons.

There are exceptions with Krypton, Xenon, and Radon though.

Yes. All noble gases are mono atomic. Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Neon is commonly used in signs due to its bright and colorful glow when an electric current is passed through it.

It means that the atom or ion has the same number of electrons as a noble gas, thus adopting the stable electron configuration of the noble gas. This typically involves attaining a full valence shell of electrons. This concept is used in chemistry to describe similarities in chemical behavior between the atom or ion and the noble gas.

Elements like neon and argon are nonreactive because they have stable electron configurations with full outer electron shells. This makes them very unwilling to gain, lose, or share electrons with other atoms, leading to their inert nature.
