The rate of radioactive decay is directly proportional to the stability of the:
- A
Medium
- B
Atmosphere
- C
Isotope
- D
Half life
For a given number of atoms, isotopes with shorter half-lives decay more rapidly, undergoing a greater number of radioactive decays per unit time than do isotopes with longer half-lives.
That's an incorrect option. The phenomenon of radioactive decay is spontaneous and doesn't depends on factors such as medium present or temperature and pressure of the medium.
That's an incorrect option. The phenomenon of radioactive decay is spontaneous and doesn't depends on factors such as atmosphere or medium present.
That's a correct option.For a given number of atoms, isotopes with shorter half-lives decay more rapidly, undergoing a greater number of radioactive decays per unit time than do isotopes with longer half-lives.
That's an incorrect option. The phenomenon of radioactive decay doesn't depends on the half life of isotopes present in the sample.
