Vedclass · Answer

(C) The mass of an electron is approximately $9.109 	imes 10^{-31} \ kg$. The lightest nucleus is the hydrogen nucleus (a proton),which has a mass of approximately $1.672 	imes 10^{-27} \ kg$. The ratio of the mass of an electron to the mass of a proton is $\frac{9.109 	imes 10^{-31}}{1.672 	imes 10^{-27}} \approx \frac{1}{1836}$. Thus,the mass of an electron is approximately $\frac{1}{1840}$ of the mass of the lightest nucleus (proton).

The mass of an electron is ......... compared to the mass of the lightest nucleus.
