Chapter 25.1, Problem 8LC

Interpretation Introduction

Interpretation: To predict the isotope, when polonium-210 decays by alpha radiation.

Concept Introduction: The process which involves the formation of more than one nuclide via a collision between two nuclei or between one nucleus and a subatomic particle, is known as a nuclear reaction.

Answer to Problem 8LC

The isotope that is formed when polonium-210 decays by alpha radiation is Lead-206.

Explanation of Solution

Alpha decay: The radiation that emits an alpha particle (Helium nuclei) is known as alpha radiation. An alpha particle comprises two protons and two neutrons and also consists of a double positive layer.

The chemical equation depicting when polonium-210 decays by alpha radiation is as follows:

  $\text{P}\text{o}\stackrel{\text{radioactive decay}}{\to }\text{P}\text{b}+\text{H}\text{e}$

Polonium-210 decays into Lead-206 during alpha radiation.

Conclusion

Thus, the isotope that is formed when polonium-210 decays by alpha radiation is Lead-206.
