Electron – volt is the unit of energy (1 eV = 1.6

\times {10^{ - 19}}J)

. in H-atom, the binding energy of electron in first orbit is 13.6 eV. The same in joule (J) is

View answer and explanation

Correct option: B

21.76 \times {10^{ - 19}}J

Option B (

21.76 \times {10^{ - 19}}J

) is correct because it's the result of converting the binding energy from electron-volts to joules using the given conversion factor.
