What is the mass number of hydrogen three?
3.0160492
Tritium (hydrogen-3), has an atomic mass of 3.0160492, and it consists of one proton and two neutrons.
What does the 3 in hydrogen 3 mean?
Tritium
Tritium (/ˈtrɪtiəm/ or /ˈtrɪʃiəm/, from Ancient Greek τρίτος (trítos) ‘third’) or hydrogen-3 (symbol T or 3H) is a rare and radioactive isotope of hydrogen. Tritium is also used as a nuclear fusion fuel, along with more abundant deuterium, in tokamak reactors and in hydrogen bombs.
Why the mass number of hydrogen is 1?
Hydrogen is the first and the lightest element of the periodic table, which contains only 1 electron, and so has an atomic number of 1. Apart from 1 electron, an isolated hydrogen atom contains 1 proton, and no neutrons. As this factor is simplified as 1.007 amu, therefore, hydrogen has a mass of 1.007 amu.
How do you find the mass number of hydrogen?
The atomic mass number is the sum of all protons and neutrons in the nucleus. The hydrogen atom may contain a neutron, but it usually doesn’t, so the mass number of hydrogen is 1.
What is the mass of hydrogen isotopes?
Hydrogen
| Isotope | Atomic mass (Da) | Isotopic abundance (amount fraction) |
|---|---|---|
| 1H | 1.007 825 0322(6) | [0.999 72, 0.999 99] |
| 2H | 2.014 101 7781(8) | [0.000 01, 0.000 28] |
How do the isotopes hydrogen 2 and hydrogen-3 differ?
All three forms have one proton (pink) and one electron (dark green) but differ in the number of neutrons (gray) in the nucleus. Protium, or ordinary hydrogen (top), has no neutrons. Deuterium, or hydrogen-2 (bottom left) has one neutron. Tritium, or hydrogen-3 (bottom right) has two neutrons.
How is hydrogen 3 produced?
Tritium (abbreviated as 3H) is a hydrogen atom that has two neutrons in the nucleus and one proton. Tritium is produced naturally in the upper atmosphere when cosmic rays strike nitrogen molecules in the air. Tritium is also produced during nuclear weapons explosions, and as a byproduct in nuclear reactors.
When hydrogen 3 beta decays what is produced?
helium-3
The chemical properties of tritium are essentially the same as those of ordinary hydrogen. It decays with a half-life of 12 years by emitting a beta particle to produce helium-3. Tritium has a relatively high specific activity and is generated by both natural and artificial processes.

How do the isotopes of hydrogen 2 and hydrogen-3 differ?
The image shows the three isotopes of the element hydrogen. All three forms have one proton (pink) and one electron (dark green) but differ in the number of neutrons (gray) in the nucleus. Deuterium, or hydrogen-2 (bottom left) has one neutron. Tritium, or hydrogen-3 (bottom right) has two neutrons.
