Chapter 19, Problem 13A

(a)

Interpretation Introduction

Interpretation: The given equation for nuclear reaction needs to be balanced.

Concept Introduction: Nuclear reactions can be expressed similarly to that of chemical equations. The transformations of particles follow certain conservation laws. In balance a nuclear equation, the atomic numbers and mass number of all species on either side of the arrow must be equal.

Answer to Problem 13A

The balanced nuclear equation: 89210Ac 24He + 87206Fr

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=89A=892A=87

Atomic number 87 corresponds to Francium.

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

According to conservation of mass number,

  M+4=210M=2104M=206

So, the balanced nuclear equation: 89210Ac 24He + 87206Fr

Answer to Problem 13A

The balanced nuclear equation: 53131I 54131Xe + 1 0e

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+54

According to conservation of atomic number,

  A+54=53A=1

So, the missing element is beta particle.

Similarly, total mass number on right side of the equation is =M+131

  M+131=131M=0

So, the balanced nuclear equation: 53131I 54131Xe + 1 0e

Answer to Problem 13A

The balanced nuclear equation: 3588Br 3587Br + 01n

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+35

According to conservation of atomic number,

  A+35=35A=0

Similarly, total mass number on right side of the equation is =M+87

  M+87=88M=1

So, the missing particle is neutron. The balanced nuclear equation: 3588Br 3587Br + 01n
