Consider the nuclear equation below. 222/66Rn--&gt;218/?Po+4/2He Which is the missing value that will balance the equation? 84 8
erastovalidia [21]
<h3>Answer:</h3>

84

<h3>Explanation:</h3>
  • The nuclear equation shows the decay of Radon-222 by emitting an alpha particle to form polonium-218.
  • When a radioactive isotope undergoes alpha-decay, the mass number is decreased by 4 while the atomic number decreases by 2.
  • Therefore, the complete nuclear equation is;

²²²₈₆Rn → ²¹⁸₈₄Po + ⁴₂He

  • The atomic number of Radon-222 decreases from 86 to 84 while the mass number decreases from 222 to 218, forming polonium-218.
