Is he2 helium gas?
Helium is a chemical element with symbol He and atomic number 2. Classified as a noble gas, Helium is a gas at room temperature.
Is molar mass and atomic mass same?
Molar masses of the elements are the same numeric value as the masses of a single atom in atomic mass units but in units of grams instead. Molar masses of compounds are calculated by adding the molar masses of their atoms.
How do you write helium-4?
The total spin of the helium-4 nucleus is an integer (zero), and therefore it is a boson (as are neutral atoms of helium-4)….Helium-4.

Why is He2 not stable?
According to MOT;The bond order and stabilization energy of he2 molecule are zero. He2 molecule contains 4 electrons. Each atom gives 2 electrons in 1s orbitals. This indicates that there is no bond formation between 2 HE atoms and hence the He2 molecule does not exist.
