Deep sea divers breath helium and oxygen, helium is also used to inflate party balloons and airship blimps.
unknown Helium.....the most uplifting experience a balloon can get.
Math teachers.
it is also used as a filler for paint.
The alpha particle is a helium nucleus. Its symbol is 24He2+, meaning 2 protons, 2 neutrons, and no electrons.
most stars are made of mainly hydrogen, a little helium and traces of other gases like oxygen

Helium has two protons and two neutrons (and two electrons).
Helium, carbon, and potassium are all chemical elements found on the periodic table. They each have distinct properties and uses in various applications.
helium and hydrogen
Stars contain hydrogen, helium and a little iron.
Isotopes in helium are not typically important because the most common isotope, helium-4, is stable and abundant. Helium-3, another isotope, is less common and has some specialized uses in scientific research and certain high-tech applications.
Helium-4 has 2 protons and 2 neutrons. The less common helium-3 has 2 protons but only 1 neutron. There are also several additional isotopes (that is, different number of neutrons), but those are unstable (radioactive).
A helium-4 nucleus has 2 protons, 2 neutrons, and 2 electrons. It is the most common and stable isotope of helium found in nature.

In a helium atom, you would typically find 2 neutrons. Helium has an atomic number of 2, meaning it has 2 protons in its nucleus which are balanced by 2 neutrons to maintain stability.
