The mass of a proton is and the mass of an electron is . If the ratio is approximately expressed as — Atomic Structure Chemistry Question
Question
The mass of a proton is $m_p$ and the mass of an electron is $m_e$. If the ratio $\frac{m_p}{m_e}$ is approximately expressed as an integer $x$, find the value of $x$.
Answer: 1837
💡 Solution & Explanation
The mass of a proton is $1.672 \times 10^{-27}$ kg, while the mass of an electron is $9.1 \times 10^{-31}$ kg. The ratio of their masses is $\frac{1.672 \times 10^{-27}}{9.1 \times 10^{-31}} \approx 1837$. [5, 36, 37]
