Noble Gases

Noble gases are non polar like all other elements.

It should loose 2 electrons to become a noble gas.

Helium is placed in group 8 (or 18) of the periodic table because it has a full outer electron shell, making it stable like the other noble gases in that group. Despite having only two valence electrons, helium achieves a stable electron configuration by having a full first electron shell.

Helium gas serves as the active medium in a He-Ne laser. It provides population inversion between energy levels, allowing for laser action. The helium gas helps to excited the neon atoms to produce laser light at a wavelength of 632.8 nm.

Well...it's because they're not the same balloons.

There is a product out there called Super Hi-Float. You coat the inside of a balloon destined to be filled with helium with it, and it helps seal the pores of the latex hence holding the helium in longer.

You probably wouldn't do this with a balloon you're going to fill with CO2.

Helium is not produced industrially because it is a non-renewable resource that is extracted from natural gas deposits. The process of extracting and purifying helium is complex and costly, making large-scale industrial production inefficient. Additionally, helium is produced as a byproduct of natural gas extraction, so it is not economically viable to produce it in isolation.

The process is called nuclear fusion. It occurs in the core of stars, including our sun, where hydrogen atoms combine to form helium, releasing energy in the form of light and heat.

An atom of calcium has 20 protons in its nucleus, while an atom of neon has 10 protons. Calcium typically forms ionic bonds in compounds, while neon is a noble gas that does not typically bond with other elements.

Neither.

Aluminium is a group 13 metal or a main group metal.

Beryllium has 4 electrons and is not isoelectronic with any noble gas. However Be2+ is isoelectronnic with helium.

I am unsure what you mean by the formula for Hydrogen and Helium because both are an element, not a compound and you would generally not have a formula for an element. However, I can tell you that the difference between the formula for Hydrogen gas and Helium gas if;

Hydrogen gas: H2 H-H

Helium gas: He

Hope this helps

Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.

Argon makes up about 0.06% of the Earth's crust by weight. It is a relatively minor component compared to other elements like oxygen, silicon, aluminum, and iron.

Krypton (Kr) has the same Lewis structure as Se2. Both molecules have 16 valence electrons arranged in a linear structure with a single covalent bond.

Helium does not have a gender, I don't know what you think either of those mean but helium is that stuff you put in a balloon and when you suck it up it makes your voice really high, and gender means what sex a person or animal is (male or female)

1 mole atoms of all atoms of any element will always have the same number of atoms and will be equal to 6.023 x 1023 atoms. However the weight will vary.

1 mole = 4 g of Helium or 197 g of gold or 207 g of lead

The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital. So, the main difference is that hydrogen has one electron in its outer shell while helium has two electrons in its outer shell.

The amount for a noble prize is determined by the Nobel Foundation, which manages the Nobel Prizes. The specific amount can vary each year, but it usually consists of a monetary award, a diploma, and a gold medal.

Flexibility and brittleness are properties of solids. Because of its very unusual quantum properties (compared to nearly all other elements - hydrogen is weird too) flexibility and brittleness may not really apply to solid helium.

Helium CAN be turned into a solid - but it requires elevated pressures and REAAALLLY low temperatures. Because of quantum effects, it can remain liquid all the way to absolute zero at normal pressures. To get a solid requires pressures above about 2.5 MPa (25 bar) and temperatures down around 1 Kelvin. In theory you could get it solidify at room temperature if you could get it up to a pressure of 114,000 atmospheres (1,675,338 psi) but well before those pressures helium tends to diffuse into whatever solid forms the walls of its container - causing embrittlement, leading to fractures - aaaaannnnnnddddd - POW!

Suffice it to say that at such extreme temperatures flexibility is difficult to measure. At least one experiment found no penetration of a probe 0.6-mm in diameter until the force exerted exceeded 330 dyne - at which point it gradually penetrated the sample at a rate of about 3 µm/sec. As soon as the probe was withdrawn, the indentation "healed" - kind of like rubber rebounding after compression, but in this case it more like the helium flowing back into the depression. Apparently solid helium doesn't so much flex as flow.

Brittleness usually is defined as the response to stresses. As already noted, it sort of flows when subject to compressive stress. Solid helium als behaves strangely under shear stresses. It can be a "supersolid", i.e. a solid exhibiting superfluid characteristics like zero viscosity flow, consequently when placed under shear stress it may decouple from the the shearing surface making any measurements meaningless.

4 g of He = 1 mole.

So, 30.8 g = 7.7 moles

Helium is a noble gas with a full outer shell of electrons, making it highly stable and unreactive. Its electron configuration does not readily lend itself to forming chemical bonds with other elements to create compounds.

1 mole = 20.18 g of Neon = 6.023 x 1023 atoms of neon (A neon molecule has only one atom)

So, 39 moles = 39 x 6.023 x 1023 atoms = 234.897 x 1023 atoms of neon

No, aluminum is a metal and helium is a noble gas. Noble gases are a group of unreactive elements with a full valence shell, while aluminum is a reactive metal commonly used in various applications due to its properties.
