A proton has a mass of 1. So Hydrogen, being the first element, has a mass of 1. Chemists hypothesised, that the proton (being almost 2000 times heavier than the electron) contributed all the mass of an atom. As such, an element like helium, which has 2 protons, would be twice as heavy as a hydrogen atom. However, it was found that it was 4 times as heavy compared to hydrogen. Why is this?

Wähle eine der folgenden:

The presence of dark energy.
The existence of an uncharged subatomic particle known as a neutron.
The mass of electrons was actually incorrect, it is the same as a proton.
The helium sample in experiments may have been dirty, altering the results.
