Given:
Nuclear reaction
¹²⁴Ba₅₆ → ¹²⁴Cs₅₅ + ?
To determine:
The product that would complete the nuclear reaction
Step-by-step 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
