Which one of the following notations shows the product correctly? — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

We verify the conservation of mass and atomic numbers for each. (b) $10+4 = 13+1$ (mass); $5+2 = 7+0$ (atomic). Correct. (c) $14+1 = 14+1$ (mass); $7+0 = 6+1$ (atomic). Correct. (d) $28+2 = 29+1$ (mass); $14+1 = 15+0$ (atomic). Correct. Option (a) fails mass balance ($242+4 \neq 243+2$). Therefore, correct answer is B,C,D.
