Vedclass · Answer

(A) The ionisation potential is defined as the potential difference through which an electron must be accelerated to acquire enough energy to remove the most loosely bound electron from an atom.By definition,if the ionisation potential of an atom is $V$ volts,the energy required to remove the electron is $E = qV$,where $q$ is the charge of an electron $(e)$.Therefore,the energy required to ionise the helium atom is $24.6 \, eV$.

If the ionisation potential of a helium atom is $24.6 \, V$,the energy required to ionise it will be
