Which of the following is an isotope of hydrogen?
- A)\(^4_1H\)
- B)\(^5_1H\)
- C)\(^3_1H\)
- D)\(^6_1H\)
Correct Answer: C)\(^3_1H\)
Explanation
Hydrogen (\(^1H\)) has three naturally occurring isotopes, sometimes denoted \(^1H\), \(^2H\), and \(^3H\). The first two of these are stable while \(^3H\) has a half-life of 12.32 years. All heavier isotopes are synthetic (not naturally occurring, synthesized in the lab) and have a half-life less than one zeptosecond (\(10^{-21}\) second). Of these, \(^5H\) is the most stable, and \(^7H\) is the least.Post an Explanation Or Report an Error
