The charge on neutron is_______________?
Correct answer: B. Zero
- A. Plus 1.6 x 10^-19C
- B. Zero
- C. Minus 1.6 x 10^-19C
- D. No definite charge
Explanation
A neutron is electrically neutral, so its charge is 0 C. The likely mistake is choosing +1.6 x 10^-19 C or -1.6 x 10^-19 C, which are the charges of a proton and an electron respectively.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
