10 gm of a radioactive element is kept in a container. The element is -active. Then after one half-life:
(molar mass of the substance is 100 gm, Avogadro's number per mole)
(molar mass of the substance is 100 gm, Avogadro's number per mole)
View answer and explanation
Correct option: C
If all particles leave the container then the charge of the substance left is 4800 C
Option C is correct because after one half-life, half the radioactive material decays, and if all beta particles leave, the remaining substance will have a positive charge due to the loss of negative beta particles.
