Question

What is the order of the size of the atom?

Options

• \[10^{-15}\,\mathrm{m}\]

• \[10^{-10}\,\mathrm{m}\]

• \[10^{-7}\,\mathrm{m}\]

• \[10^{-14}\,\mathrm{m}\]

Answer 1

The size of the atom is of the order of \[10^{-10}\,\mathrm{m}\]. The nucleus is much smaller, with a size of the order of \[10^{-15}\,\mathrm{m}\text{ to }10^{-14}\,\mathrm{m}\].
