Question

what is the main difference between protons and neutrons? protons have a much smaller mass than neutrons. protons have a much larger volume than neutrons. protons have an electrical charge, but neutrons have no protons make up the nucleus, but neutrons orbit around

Explanation:

Protons carry a positive electrical charge (+1 elementary charge), while neutrons are electrically neutral with no charge. Mass - wise, they are very close in mass. Volume is not a typical distinguishing factor in this context, and both protons and neutrons are found in the nucleus of an atom.

Answer:

Protons have an electrical charge, but neutrons have no charge.
