Which one of the following is not correct?

Options

  1. AIn forward biased condition diode conducts
  2. BIf the packing fraction is negative, the elelment is stable
  3. CBinding energy is the energy equivalent to mass defect
  4. DRadioactive element can undergo spontaneous fission

Correct answer

D. Radioactive element can undergo spontaneous fission

Step-by-step solution

We know that, (i) In forward biased condition diode conducts. (ii) Smaller the value of packing fraction, the element is more stable similarly if the packing fraction is negative the element is stable. (iii) Binding energy is the energy equivalent to mass defect. (iv) Very few radioactive element can undergo spontaneous fission but not each element.
