AnswerIm telling your teacher "Ms.Byrd" your in 8th grade and go to berry middle?
Explanation:
In order to solve this question, we must apply the conservation of mass. The total number of nucleons (upper number) and protons (lower number) must be equal before and after the decay. The new nucleon number is
218 - 4
= 214
And new proton number is
84 - 2
= 82
Next, we must identify which element has the proton number 82. That would be lead, Pb.
Therefore, the answer is
5. ²¹⁴Pb₈₂
What are the variables you have? I can't answer if I don't know? Haha. :)
