helium is a noble gas, so it is stable and does not need to bond with anything. i think there are 7 diatomics, hydrogen and some halogens?? not positive on that. its just a short list that you pretty much have to memorize though.

What is the gas which exists as a monatomic molecule?
All elements can be a gas. Some common elements that are gas at room temperature include: Oxygen, Nitrogen, Hydrogen, Helium, Neon, Argon, Krypton, Xenon, and Fluorine.
When helium is add to a balloon does the molecules become larger?
No. Helium is not molecular it is a monoatomic gas.
Is helium a reactive molecule?
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
Atomicity of a gas?
Atomicity of a gas is the number of an element present in one molecule of that element.The gases can be:-monoatomic .E.g-Helium(He),diatomic,E.g-Hydrogen(H2),triatomic,E.g-Ozone(O3),polyatomic,E.g-Sulphur(S8).
How He (helium-3) contains two protons and one neutron in the nucleus. If neutral how many electrons orbit a He atom Is He an element atom ion and-or molecule How do you know?
Helium is a chemical element and the neutral atom has two electrons.Helium is a monoatomic gas in normal condition but the molecule He2 can be obtained.Helium can form ions as He(+) or He(2+).
Is He a molecule?
Helium is monoatomic.
Is He diatomic molecule?
Helium is monoatomic.
Is helium a compound molecule?
Helium is a chemical element, not a compound; also helium is monoatomic.
What is the gas which exists as a monatomic molecule?
All elements can be a gas. Some common elements that are gas at room temperature include: Oxygen, Nitrogen, Hydrogen, Helium, Neon, Argon, Krypton, Xenon, and Fluorine.
When helium is add to a balloon does the molecules become larger?
No. Helium is not molecular it is a monoatomic gas.
Is helium a reactive molecule?
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
Is helium element or compound?
Helium itself is an element and it forms no chemical compound whatsoever, therefore, it is a noble gas. The atom of Helium is so inert that it cannot even form a molecule with another atom of Helium, hence is monoatomic.
Is a helium a compound?
Helium is not a compound, it is an element.
Is sodium a monoatomic molecule?
Yes.Sodium is a monoatomic molecule
Is He2 joined by a double covalent bond?
He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)
Atomicity of a gas?
Atomicity of a gas is the number of an element present in one molecule of that element.The gases can be:-monoatomic .E.g-Helium(He),diatomic,E.g-Hydrogen(H2),triatomic,E.g-Ozone(O3),polyatomic,E.g-Sulphur(S8).
The elements that exists as monoatomic molecule?
Helium, neon, argon, krypon, silver, xenon, gold, mercury, radon and ununoctium.
