Among the isotopes of all the elements (radioactive as well as non-radioactive), the n/p ratio is mi — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

For protium (${}_1\text{H}^1$), the number of neutrons is 0 and the number of protons is 1. Thus, the n/p ratio is 0, which is the absolute minimum possible. Therefore, correct answer is A.
