Which of the following statements correctly describes the relative size of subatomic particles?



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


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


- Protons have the largest mass and electrons and neutrons are similar in relative size.


- Protons are the largest and most dense particles, electrons are dense but not very large, and neutrons are neither dense nor large in size

Answer 1

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

Answer 2

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

Step-by-step 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.
