The ionisation energy of second electron in helium atom is A 100eV B 27 2eV C 13 6eV D 54 4eV heyl am confused from this question mujhe pata hai electron ko remove karane ke liye ionisation energy 54 4 ev di jaayegi but I am confused whe he ask of 2nd electron ionisation energy in helium mujhe janna tha ki ionisation energy of 1st electron and 2 electron me difference hai kya kuch
