What is one atom of noble gas?

For example one atom of helium, one atom of argon etc.; all atoms contain a nucleus (formed from protons and neutrons) and a cloud of electrons.


What do argon and helium form?

Argon and helium are both noble gases, which are generally inert and do not readily form chemical bonds with other elements. Therefore, argon and helium do not typically form chemical compounds with each other or with other elements.


How many protons are in the nucleus of Ar atoms?

It depends on the identity of the atom. For example, Hydrogen has one proton, but Helium has two.


How do you separate helium and argon to get helium?

To get helium you can use fractional distillation of liquid air.-or-If you just wanted to separate helium from a MIXTURE of helium and argon you could use diffusion. Since helium is lighter than air while argon is heaver than air. You can capture the helium as it "diffuses" away from argon.


Is 1 helium atom an atom?

Helium is an element- the second one in the periodic table.


Is Ar a atom or molecule?

Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.


How many kinds of atoms does helium have?

Helium has one kind of atom: helium.


Does an atom of helium have eight electrons in its outer energy level?

the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons


Is helium argon krypton or neon a weaker Van der Waals force?

Helium has the weakest Van der Waals forces among these noble gases. This is because helium is a monatomic gas, meaning it has only one atom per molecule, resulting in weaker Van der Waals interactions compared to larger noble gases like argon, krypton, and neon.


What two atoms are joined together to form a helium atom?

"Atom" implies there's only one there. If there were more than one atom, you'd have a compound. Since helium's an element, all that's in it is helium.


What is one of the noble gases?

Helium, Neon, Argon, Krypton, Xenon, Radon


Why helium is an element?

Helium is an element because it contains only one atom in its simplest form.
