"There is proton neutron and electron in atom"

Translation: Kuna protoni nutroni na elektroni katika atomu

[DavidTeepl1]

The English translation is ungrammatical. Should be, "There are protons, neutrons and electrons in an atom."

[AGreatUserName]

Or if we're talking about a specific deuterium atom, "There is a proton, a neutron and an electron in the atom."

[Ernst557459]

Or if we're talking about hydrogen, the statement would be incorrect :)
