A. Protons are the same size as neutrons. Both are bigger than electrons.

Answer: The correct answer is: A. Protons are the same size as neutrons. Both are bigger than electrons.

Explanation:

Protons are practically the same size as neutrons, and both are much larger than electrons. A proton has a mass approximately 1,836 times greater than the mass of the electron, but the masses of protons and neutrons differ less than one percent. A proton has a mass of 1.6726 x 10-24grams.
