Der Kern eines Heliumatoms enthält zwei Protonen.

To describe the composition of an atomic nucleus, German frequently uses „bestehen aus“ (to consist of). The dative follows „aus“, including in quantity expressions with „Proton“ (proton).
Der Kern dieses Wasserstoffatoms besteht aus einem Proton.
The nucleus of this hydrogen atom consists of one proton.
In chemistry, „ein Proton abgeben“ (to donate a proton) and „ein Proton aufnehmen“ (to accept a proton) are typical collocations. They are especially common when describing reactions between acids and bases.
Bei dieser Reaktion gibt die Säure ein Proton ab, und die Base nimmt es auf.
In this reaction, the acid donates a proton, and the base accepts it.
In texts about particle accelerators, the collocations „Protonen beschleunigen“ (to accelerate protons) and „Protonen zur Kollision bringen“ (to bring protons into collision) are common. Here, „Proton“ refers to a particle that can also move outside an atomic nucleus.
In der Anlage werden Protonen beschleunigt und anschließend zur Kollision gebracht.
At the facility, protons are accelerated and then brought into collision.
