I think it is hydrogen
Helium is itself a chemical element and therefore is not found in any other chemical element.
The universe is mostly comprised of empty space and therefore the helium is found in certain places. It is found on Earth and some other planets, but it is most commonly found in stars such as the Sun.
hydrogen is most commonly found as a part of water with oxygen.
this is a guess but beryllium?
helium is chemically inert and is not found in any materials
Helium is one element and does not chemically react.
No. helium is chemically inert and does not combine with other elements.
The main element found in the atmosphere of a gas giant planet like Jupiter or Saturn is hydrogen. This element makes up the majority of their composition, along with other gases like helium, methane, and ammonia.
Basically all of them. However, most stars contain large amounts of hydrogen (since that's the most common element in the Universe), as well as helium, as well as smaller amounts of other elements.
No. Helium is an element, which makes it a pure substance.
Helium is chemically inert; it does not combine with any other element.
Na represents the chemical element sodium. Neon, helium, and argon are other elements on the periodic table. Sodium is a reactive metal commonly found in salt compounds.
