General Science Chemistry MCQs

Q.  Which of the following is correct combination of masses of the three sub-atomic particles?

a. Electron – 0. 00055 amu; Proton – 1.0078 amu; Neutron – 1.0083 amu
b. Electron – 0. 00055 amu; Proton – 1.0083 amu; Neutron – 1.0078 amu
c. Electron – 0. 00055 amu; Proton – 1.0078 amu; Neutron – 1.0078 amu
d. Electron – 0. 00055 amu; Proton – 1.0083 amu; Neutron – 1.0083 amu


ANSWER: See Answer
 
The correct mass of Electron is 0. 00055 amu; Proton is 1.0078 amu and Neutron is 1.0083 amu. Kindly note mass of neutron is slightly more than that of Proton.
