<u>Answer:</u> The isotopic symbol of barium is and that of strontium is
<u>Explanation:</u>
Nuclear fission reactions are defined as the reactions in which a heavier nuclei breaks down in two or more smaller nuclei.
In a nuclear reaction, the total mass and total atomic number remains the same.
- For the given fission reaction:
- <u>To calculate A:</u>
Total mass on reactant side = total mass on product side
235 + 1 = A + 94 + 3
A = 139
- <u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
92 + 0 = Z + 36 + 0
Z = 56
The isotopic symbol of barium is
- For the given fission reaction:
- <u>To calculate A:</u>
Total mass on reactant side = total mass on product side
235 + 1 = A + 143 + 3
A = 90
- <u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
92 + 0 = Z + 54 + 0
Z = 38
The isotopic symbol of strontium is
Hence, the isotopic symbol of barium is and that of strontium is
