Chemical symbol (not formula) of hydrogen is H and for helium is He.
I am unsure what you mean by the formula for Hydrogen and Helium because both are an element, not a compound and you would generally not have a formula for an element. However, I can tell you that the difference between the formula for Hydrogen gas and Helium gas if; Hydrogen gas: H2 H-H Helium gas: He Hope this helps
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.
The formula of the hydride formed by helium is HeH+. It's a cationic species known as the helium hydride ion, which is formed when helium reacts with hydrogen ions in very low-temperature environments such as interstellar space.
The symbol for hydrogen is H, and the symbol for helium is He.
Hydrogen and helium
Hydrogen is H2. Helium is He.
No. Helium and Hydrogen are two different elements.
Hydrogen and helium are formed in Sun.
No, helium is almost 4 times as heavy as hydrogen.
About 96% is hydrogen, about 3% helium.
helium
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
