The mass of an electron is _ times smaller than that of a proton.
Correct answer: A. 1836
- A. 1836
- B. 1839
- C. 1837
- D. 1834
Explanation
The mass of an electron is indeed significantly smaller than the mass of a proton. The electron has a mass of approximately 9.10938356 × 10-31 kilograms (kg), while the proton has a mass of approximately 1.6726219 × 10-27 kg. The ratio of the mass of an electron to the mass of a proton is approximately 1/1836. The mass of an electron is 1836 times smaller as compared to a proton. (This line is mentioned in PTB as well as Federal.)

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
