Question

Neutrons have a mass equal to ______ but have ______ electric charge.

• A. protons
• B. no

Answer 1

• Mass of a proton = 1.672 ×10^-24 g
• Mass of a neutron = 1.674 ×10^-24 g

It can be seen from the values given above that the mass of a neutron is almost similar to the mass of a proton.

While protons are positively charged, neutrons have no charge on them and are therefore called electrically neutral.

Therefore, neutrons have a mass equal to protons but have no electric charge.
