Chapter 15, Problem 17RQ

Solution

To determine: The number of nucleons in the hydrogen-3 atom

Answer:

Hydrogen-3 is also known as tritium contains 3 nucleons; one is a proton and 2 are neutrons in its atom.

Explanation:

The hydrogen atom is the lightest in the periodic table and is placed at the first position in the periodic table because it has 1 proton in its nucleus.

The tritium, also known as Hydrogen-3, is a radioactive isotope of hydrogen. The number of protons in Hydrogen-3 is 1, and the number of neutrons in its nucleus is 2. Thus, it has a mass number equal to 3. Tritium is rare and can be used in radioactive tracing instruments and fuel in nuclear fusion.

The nucleus of tritium contains one proton and two neutrons. The atomic number of tritium is the same as other forms of hydrogen, but due to different neutrons in its nucleus makes it different from other forms in respect of their nuclear properties.

Conclusion:

Therefore, hydrogen-3 is also known as tritium contains 3 nucleons; one is a proton, and 2 are neutrons in its atom.
