No. Helium and Hydrogen are two different elements.
The main two are hydrogen and helium.
The two main gases found in the Sun are hydrogen and helium. Hydrogen makes up about 74% of the Sun's mass, while helium makes up about 24%.
no they are different elements
Mostly hydrogen and helium.
helium and hydrogen
no it has hydogen and helium but it makes heat and light
The formula for hydrogen gas is H2, indicating that it is composed of two hydrogen atoms bonded together. The formula for helium gas is simply He, as helium exists as single atoms and does not form bonds with itself or other elements in its elemental state.
Hydrogen and Helium
Hydrogen is the most common element in the universe as a whole; about 75% of the universe by mass is hydrogen (since hydrogen is also the lightest element, that means that the percentage by number of atoms is even higher) . Helium is second; oxygen is a fairly distant third.
Saturn is primarily composed of hydrogen and helium. It is estimated that about 75-90% of Saturn's mass consists of hydrogen, while helium makes up most of the remaining mass, along with traces of other elements.
(H) Hydrogen makes up the majority of the Sun and Jupiter with small amounts of He (Helium)
