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

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

Explanation:

Protons and neutrons both are parts of nucleus and they stay inside the nucleus due to large nuclear force between them

Mass of proton and mass of neutron is almost same or in more precisely we can say that neutrons are slightly heavy than protons

mass of neutrons is 1.008 amu while mass of protons are 1.007 amu.

the main different between them is that protons are positively charged and their charge is same as that of charge of electron

while neutrons are electrically neutral and they do not have any charge on them.

so correct answer will be

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

tube or goog with be a great resource to with that question

cant without the picture! ?
