Water is a compound of hydrogen and oxygen.
Neptune's atmosphere is made up of hydrogen, helium, and methane.
because they are Diatomic molecule. H2, O2 etc.
Yes for sure, but in the very small amount, the composition of air is approximately : 78.08 % Nitrogen 20.94 % Oxygen 00.93 % Argon 00.03 % Carbon Dioxide which is equal to 99.98 percent the rest of the air is compose of Neon Helium Krypton Sulfur dioxide Methane Hydrogen Nitrous Oxide Xenon Ozone Nitrogen dioxide Iodine Carbon monoxide Ammonia In which Helium's composition is 5.2 parts per million.
Helium is an element. It is a chemical element with the symbol He and atomic number 2. Helium exists as individual helium atoms, not molecules.
Helium is a chemical element, not a compound; also helium is monoatomic.
Hydrogen is used to create water: H20. Two hydrogen molecules and one oxygen molecule create water. Also the sun is mostly made of hydrogen and helium.
no. it does not
No. Helium consists of individual atoms and does not form molecules or compounds.
If HE was a compound it would be a compound of H (hydrogen) and E (sorry there is no such element).If HE is an element then it is misspelled and should be He (helium).
Helium does not form molecules but exists as individual atoms.
Jupiter and Saturn - HYDROGEN and HELIUMUranus and Neptune - Water, Ammonia and Methane.
Water is a compound of hydrogen and oxygen.
No. Helium does not combine with anything. It is inert.
Neptune's atmosphere is made up of hydrogen, helium, and methane.
No, it is formed by fusion of hydrogen and helium molecules.
Helium is an atom. Heavier elements have molecules.
