Ratio of the weight of H-atom to that of an electron is approximately______________?
Correct answer: B. 1836
- A. 18.336
- B. 1836
- C. 18360
- D. 183.6
Explanation
The weight ratio is approximately the mass ratio because both objects experience the same gravitational acceleration: Wh/We = mhg/meg = mh/me. Using the proton-to-electron mass ratio gives approximately 1836, which is dimensionless. The likely mistake is choosing 183.6, which results from shifting the decimal point by one place.

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.
