iogann1982 [59]

Answer:

C- A proton has about the same mass as a neutron .

In an atom such as a carbon atom, the masses of the proton and neutrons are the same.

The mass of the electrons is very negligible.

  • Protons are the positively charged particles in an atom
  • Neutrons do not carry any charges
  • Both protons and neutrons have similar masses.
  • They contribute the bulk of the mass of the atom.
  • The electrons carry negative charges and they have negligible masses.

The mass of protons and neutrons are similar.
