The mass of a neutron is equal to the mass of a proton plus the mass of an electron. A. True
B. False

B. False

Explanation:

The mass of a neutron is nearly the same mass of a proton whereas the electron is much less massive.

Exact masses are:

Neutron = 1.6749286x10²⁷ kg

Proton = 1.6726231x10⁻²⁷ kg

Electron = 9.1093897x10⁻³¹ kg

The mass of a proton plus the mass of an electron is:

1.6735340x10⁻²⁷ kg.

This mass is different to the mass of the neutron. Thus, the answer is:

c. 75.7

i think that is the right
