Chapter 25, Problem 79SCQ

Interpretation Introduction

Interpretation: The isotopes of radium and polonium which can be found in the uranium ore has to be determined.

Concept Introduction:

Isotopes: The two elements with same atomic number but with different mass number are considered as isotopes of each other.

In the radioactive decay process the unstable isotopes loses their energy by emitting radiation in order to attain stable species. It is converted in to stable isotopes by emitting positron ${}_{+1}^0\beta$ , gamma ${}_0^0\gamma$ , Beta $\beta$, alpha ${}_2^{4}He$ and or by electron capture ${}_{-1}^{0}e$ .
