Answer:
The correct option is (D) 2114 electrons
Step-by-step explanation:
The positive charge on a proton is equal in magnitude to the negative charge on an electron. Protons and neutrons have approximately the same mass, but protons have much more massive than electrons which are approximately 2,000 times as massive as an electron. Because protons are so much heavier than electrons, the electrons do not make a significant contribution to the mass of an atom.
