Question

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 1

The answer to your question is below

Step-by-step 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
