Consider the nuclear equation below. 124 124 > cs + ? 56 55 which completes the nuclear equation? 0/+1e 0/-1e 1/0n 1/1h

Given:

Nuclear reaction

¹²⁴Ba₅₆  →    ¹²⁴Cs₅₅ + ?

To determine:

The product that would complete the nuclear reaction

Explanation:

In order to balance the nuclear reaction, the atomic number and the mass number on the reactants and products must be balanced.

Reactant- Ba                                                Product- Cs

Mass number = 124                                    Mass number = 124

Atomic number = 56                                  Atomic number = 55

The mass number is balanced, however the atomic number in the product is deficient by 1 unit. This can be balanced by a positron i.e.  ⁰e₁

Ans (a)

¹²⁴Ba₅₆  →    ¹²⁴Cs₅₅ + ⁰e₁
