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.

Helium gas is a monoatomic molecule because it consists of individual atoms of helium, each with a full outer electron shell, making them stable and unlikely to form bonds with other atoms. This results in helium existing as single atoms rather than forming diatomic molecules like other gases such as oxygen or nitrogen.

What is helium plus helium?
When two helium atoms combine, they form a molecule of helium gas (He2), which is also known as a dihelium molecule. This molecule is quite rare and unstable under normal conditions, as helium typically exists as a monoatomic gas.
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 a noble gas and is known for its inert and non-reactive nature. It is a colorless, odorless, and tasteless gas that does not readily form compounds with other elements.
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.
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.
Is helium a compound molecule?
No, helium is an element, not a compound molecule. It is a noble gas with the chemical symbol He and atomic number 2. Helium exists as single atoms and does not form molecules.
When helium is add to a balloon does the molecules become larger?
No. Helium is not molecular it is a monoatomic gas.
Is a helium a compound?
Helium is not a compound, it is an element.
Is He2 joined by a double covalent bond?
No, He2 does not form a stable molecule with a double covalent bond. Helium is a noble gas with a full valence shell, so it prefers not to form chemical bonds with other atoms.
Is helium a reactive molecule?
No, helium is a noble gas and is known for its inert and non-reactive nature. It is a colorless, odorless, and tasteless gas that does not readily form compounds with other elements.
Is helium element or compound?
Helium is an element. It is a noble gas with the atomic number 2 and is the second lightest element in the periodic table. Helium exists as single atoms and does not form compounds with other elements.
The elements that exists as monoatomic molecule?
Helium, neon, argon, krypon, silver, xenon, gold, mercury, radon and ununoctium.

Is helium an ion?
Yes helium is an atom. It is stable. It is placed in group 18.Yes, helium is a monoatomic molecule. It is stable itself as it has already achieved maximum possible electrons in its outermost shell. It is the only element in group 18 without 8 electrons in valence shell.
