But look also at what has happened in the star, two light atoms have combined to make a heavier one.
In atoms lighter than atomic weight 50 it will not maintain itself, for their energy is consumed.
The lightest atom, hydrogen, gives rise to some of the most characteristic group frequencies.
Potassium is formed in the universe by nucleosynthesis from lighter atoms.
Techniques using this are most effective for light atoms such as hydrogen.
A thing may have a high temperature but because it contains very few or light atoms it has very little heat.
Fusion reactions combine lighter atoms, such as hydrogen, together to form larger ones.
All of them are highly radioactive and decay swiftly into lighter atoms.
The names, symbols and make-up of the nuclei of the light atoms.
The latter is an incorrect assumption for light atoms.
