PLEASE HELP 15 POINTS The transmutation of a radioactive uranium isotope, 234 /92 U, into a radon isotope, 222, 86 R, involves a series of three nuclear reactions. At the end of the first reaction, a thorium isotope, 230/ 90 TH, is formed and at the end of the second reaction, a radium isotope, 226/88,R.a, is formed. In both the reactions, an alpha particle is emitted. Write the balanced equations for the three successive nuclear reactions. Please show all work.

Answer:

The answer to your question is below

Explanation:

Alpha particles are a particle identical to a helium atom. Then alpha particles have an atomic number of 2 and a mass number of 4.

Reactions

First                         ²³⁴₉₂ U    ⇒    ²³⁰₉₀Th  +  ⁴₂ He

 

Second                     ²³⁰₉₀Th   ⇒    ²²⁶₈₈Ra   + ⁴₂He

Third                         ²²⁶₈₈ Ra  ⇒    ²²²₈₆ Rn  +  ⁴₂He
