Question

Which conversion relates an electron volt to joules?

पर्याय

• \[1\,\mathrm{eV}=1.6\times10^{19}\,\mathrm{J}\]

• \[1\,\mathrm{eV}=13.6\,\mathrm{J}\]

• \[1\,\mathrm{eV}=1.6\times10^{-19}\,\mathrm{J}\]

• \[1\,\mathrm{eV}=2.18\times10^{-18}\,\mathrm{J}\]

Answer 1

One electron volt equals \[1.6\times10^{-19}\,\mathrm{J}\]. This conversion allows atomic energies stated in joules to be expressed in electron volts.
