Can we see protons and neutrons?
We can never see the subatomic particles directly, but can only infer from observation of such indirect effects like tracks.
If there are many of them and they are emitting some radiation, and also if we shine some radiation on then and receive back the response this will also constitute a kind of seeing..

Answer and Explanation: The atom with the largest number of neutrons is a tie between livermorium and tennessine. Each of these atoms contain 177 neutrons. Livermorium has…
How do you figure out neutrons?
Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass). So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number.
