Answer to Problem 15A

The balanced nuclear equation:  88226Ra  86222Rn + 24He

Explanation of Solution

Let the atomic numbers and mass number of the missing element is A and M .

Total atomic number on right side of the equation is =A+2

According to conservation of atomic number,

  A+2=88A=882A=86

Atomic number 86 corresponds to Radium.

Similarly, total mass number on right side of the equation is =M+4

  M+4=226M=2264M=222

The balanced nuclear equation:  88226Ra  86222Rn + 24He
