The sun just released a burst of a rare form of helium known as helium-3 (3 He ... likely due to its unique charge-to-mass ratio." On Earth, 3 He is highly prized for its potential uses in ...

For example, a helium atom has an atomic mass of 4, but an atomic number (or positive charge) of 2. Since electrons have almost no mass, it seemed that something besides the protons in the nucleus ...

A FEW months ago, K. Peters and I published an account of experiments we had made in an attempt to transmute hydrogen into helium (Ber. d. Deutschen Chem. Ges., 59, 2039; 1926). A more or less ...

Helium is one of our few non-renewable resources, and yet it is critical for many applications as an inert gas and as one of the coldest substances known. The unique properties of this “endangered ...
