The electron shell of atoms acts as an "electromagnetic ... has now succeeded in precisely measuring the effect of this shielding in beryllium atoms. The study is published in the journal Nature.

As the outside of the shell expanded rapidly with ... temperature and the electron structure around the atomic nuclei. When the beryllium was heated and compressed, at least three of its atom ...

Beryllium-7 can decay into lithium-7 through a process in which the beryllium nucleus captures one of its own electrons. This electron is then absorbed into the nucleus, where it combines with a ...
