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."

∙ 14y agoObviously helium is used in helium balloons, however, it is used in much more. it can be used like neon and turns creamy pale peach when an electric current flows through it. it is also used in helium-neon lasers and is a replacement for hydrogen in airships.

A helium atom has by definition 2 protons, but the other things can vary. Helium atoms commonly have 2 neutrons, although this can vary with a small proportion having either 1 or 3 neutrons (very, very occasionally more or less). In a neutral atom (which is what helium is basicly all the time) there would be 2 electrons also (this can vary also but only in high-energy conditions.
The protons and neutrons can also be broken down into quarks (two up quarks and a down quark for each of the protons and two downs and an up for neutrons making 6 up and 6 down quarks altogether (usually, see above) (but I think that's a little too much detail...)
The protons and the neutrons are all together in a clump called the nucleus of the atom with the electrons moving around elsewhere (not part of of the nucleus).

What is Neptune atmosphere made of?
Neptune's atmosphere is made up of hydrogen, helium, and methane.
Why is an alpha particle sometimes referred to as a helium nucleus?
An alpha particle is made up of two protons and two neutrons; this is what a helium nucleus is made up of as well.
What are the atmosphere gasses on Uranus?
80 some % Hydrogen, 10 som % helium and 2% methane are the dominant gases.
What is helium made from?
Do you mean helium? Helium is an element, so it's made of .... helium!
What type of Atom or molecule is helium air in a balloon made up?
? :-(
Are atoms made up of helium?
No Helium is made of atoms
What is helium made up off?
Atoms of Helium !
What are the gases making up helium and oxygen?
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.
What is Neptune atmosphere made of?
Neptune's atmosphere is made up of hydrogen, helium, and methane.

How much of Jupiter is made up of helium?
10% of its atmosphere is made of heilum
What is each planet's atmosphere made of?
Mercury's atmosphere is almost nonexistent but may have a very little bit of helium, sodium, and oxygen. Venus' atmosphere is made up of carbon dioxide, nitrogen. Earth's atmosphere is made up of oxygen and nitrogen, with small amounts of carbon dioxide and other gases. Mars' atmosphere is made up of carbon dioxide, nitrogen, argon, less than 1% oxygen and carbon monoxide. Jupiter's atmosphere is made up of hydrogen, helium, and methane . Saturn's atmosphere is made up of hydrogen and helium. Uranus' atmosphere is made up of hydrogen, helium, methane, and acetylene. Neptune's atmosphere is made up of hydrogen, helium and methane.
