How many times greater is the mass of a proton compared to an electron?

• A. 1000
• B. 1836
• C. 1200
• D. 2000

Answer: (B)

The mass of a proton is approximately 1836 times greater than that of an electron. This ratio stems from fundamental properties of these subatomic particles, which play crucial roles in atomic structure. Protons, which are found in the nucleus of an atom, possess a much larger mass, allowing them to contribute significantly to the overall mass of an atom, while electrons, which are much lighter, orbit around the nucleus and influence the atom's chemical properties but do not contribute nearly as much to its mass.

Understanding this ratio is important in fields such as physics and chemistry, as it helps explain why atoms are stable and how they interact during chemical reactions. The accurate comparison between the masses of protons and electrons is vital for calculations involving atomic weight and nuclear processes.
