1. Probability = e -kt, where k= decay constant
• now, t = 1/k
• probability = e-k x 1/k = 1/e
2. Electron is not a part of nucleus. It orbits the nucleus by the electrostatic force.
3. Triton is an isotope of hydrogen. It has mass number 3 and atomic number 1, the same that of hydrogen.
• A negative beta particle is 0e-1So it doesn’t change the mass number of the parent nucleus.
4. In nuclear fission, a heavy nucleus gets bombarded to produce lighter nuclei.
5. Nuclear density is the same for all nuclei. So the ratio is one.
