Answer: The correct statement is in an atom, protons and neutrons are in the nucleus, which is surrounded by electrons.
Step-by-step explanation:
There are 3 subatomic particles that are present in an atom. They are: protons, electrons and neutrons.
Protons carry positive charge and are found inside the nucleus of an atom.
Electrons carry negative charge and are found around the nucleus in the orbits.
Neutrons does not carry any charge which means they are neutral species. They are found inside the nucleus of an atom.
Thus, the correct statement is in an atom, protons and neutrons are in the nucleus, which is surrounded by electrons.
