The atom is neutral as it has two positive protons and two negative electrons. A helium atom that has lost or gained an electron is an ion. The ion has two positive protons but one electron so it ...

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 ...

It is not the same as a helium atom as it does not contain any electrons but it is written with the same chemical nomenclature as a helium atom: \(_{2}^{4}\textrm{He}\) When a radioactive atom ...

With this in mind, I have, for a couple of years now been beating the drum about helium. I first recommended it on these pages in late 2018. Now the party is getting started. We have had the ...
