Interpretation : The charges and relative masses of the three main subatomic particles are to be determined.
Concept Introduction : Atoms are divisible in nature. Subatomic particles are the fundamental particles formed by the breaking of atoms into smaller units.
Answer to Problem 11LC
The charges and relative masses of the three main subatomic particles are as follows:
Subatomic particle | Charge | Relative mass |
Electron | -1 | 1/1840 |
Proton | +1 | 1 |
Neutron | 0 | 1 |
Explanation of Solution
Protons, neutrons, and electrons are the three different types of subatomic particles.
Electrons are negatively charged subatomic particles that orbit around the nucleus discovered by J. J. Thomson.
Protons are positively charged subatomic particles present in the nucleus discovered by Eugen Goldstein.
Neutrons are neutrally charged subatomic particles present in the nucleus discovered by James Chadwick.
The charges and relative masses of the three main subatomic particles are as follows:
Subatomic particle | Charge | Relative mass |
Electron | -1 | 1/1840 |
Proton | +1 | 1 |
Neutron | 0 | 1 |
