(a)
Answer to Problem 13A
The balanced nuclear equation:
Explanation of Solution
Let the atomic numbers and mass number of the missing element is
Total atomic number on right side of the equation is
According to conservation of atomic number,
Atomic number 87 corresponds to Francium.
Similarly, total mass number on right side of the equation is
According to conservation of mass number,
So, the balanced nuclear equation:
(b)
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.
(b)
Answer to Problem 13A
The balanced nuclear equation:
Explanation of Solution
Let the atomic numbers and mass number of the missing element is
Total atomic number on right side of the equation is
According to conservation of atomic number,
So, the missing element is beta particle.
Similarly, total mass number on right side of the equation is
So, the balanced nuclear equation:
(c)
