He is the symbol for helium
Hydrogen is H
Helium is He

Nuclear reactions in the cores of stars convert hydrogen to helium
Exosphere
The atmosphere does not have helium and hydrogen because the two gases are too light to be there. Instead they are in the exosphere, above the atmosphere.
H (hydrogen) HE (helium)
atomic symbols. such as hydrogen: H, Helium: He, etc.
H, He, and Li are the symbols for elements hydrogen, helium, and lithium, respectively.
Hydrogen and helium
They are not symbols, they are elements. The first 10 are: Hydrogen, Helium, Lithium, Borilium, Boron, Carbon, Nitrogen, Oxygen, Florine, and Neon.
Hydrogen is H2. Helium is He.
Compounds have formulas that consist of symbols for elements and ions that are included in the molecules of the compound.The symbols (letters) are those of elements. These can be found on the periodic table. For example, H is hydrogen, He is helium and so on.
