Helium is a very light element that is a gas at normal temperatures.
Almost all helium atoms contain 2 protons and 2 neutrons and can be made from protons in nuclear fusion within stars, and in thermonuclear explosions. Helium nuclei are one form of decay of radioactive elements, being released as "alpha particles."
? :-(
An alpha particle is made up of two protons and two neutrons; this is what a helium nucleus is made up of as well.

Neptune is made up of: 74% hydrogen, 25% helium and 1% methane.
Neptune's atmosphere is primarily composed of hydrogen and helium, with small amounts of methane. The methane in the atmosphere gives Neptune its blue color. Additionally, there are traces of other gases such as ammonia and water vapor.
No Helium is made of atoms
Atoms of Helium !
Helium is made up of helium and oxygen is made up of oxygen. Both helium and oxygen are elements, so they can't be broken down into anything simpler without breaking apart the atoms.

Yes. Everything is made up of atoms.
