Question

The nucleus of an atom is nearly___________________ in size in comparison to the total size of the atom.

Answer 1

The radius of the nucleus of an atom is of the order of ${10}^{-13}\mathrm{cm}.$

The radius of an atom is of the order of ${10}^{-8}\mathrm{cm}.$

$\frac{\mathrm{The}\mathrm{radius}\mathrm{of}\mathrm{the}\mathrm{nucleus}\mathrm{of}\mathrm{an}\mathrm{atom}}{\mathrm{The}\mathrm{radius}\mathrm{of}\mathrm{an}\mathrm{atom}}=\frac{{10}^{-13}}{{10}^{-8}}={10}^{-5}=\frac{1}{100000}$

Hence, The nucleus of an atom is nearly $\frac{1}{100000}\mathrm{or}{10}^{-5}\mathrm{m}$ in size in comparison to the total size of the atom.
