The only UN-stable Hydrogen isotope is Tritium,
atomic number 1 (of coarse!), mass number 3,
with 2 neutrons in nucleus,
beta- electron emitter, (max.) 0.018 MeV, half-time 12.3 yr.
Isotopes with unstable nuclei are radioactive and can undergo radioactive decay to achieve a more stable state. This decay process involves the release of radiation such as alpha or beta particles. The unstable isotopes are often used in various applications, including medicine and energy production.
No. hydrogen-3 (tritium) has a nucleus with one proton and two neutrons, and is unstable. Helium-3 has a nucleus with two protons and one neutron, and is stable.
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
In a neutral hydrogen atom, there is one electron, regardless of the isotope.
Hydrogen has three stable isotopes: protium (1H), deuterium (2H), and tritium (3H). Among these, protium is the most abundant, making up over 99.98% of naturally occurring hydrogen.
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
Hydrogen, Deuterium, Tritium
The isotopes protium (H-1) and deuterium (H-2) are stable; tritium (H-3) and artificial isotopes are unstable.
Unstable isotopes can be chemically reactive.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
hydrogen, deuterium, and tritium.
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Some isotopes are stable, others are unstable.
All the isotopes of americium are radioactive and unstable.
These isotopes are unstable and emit radiation.
Isotopes of hydrogen are Hydrogen-1 (protium), ‎Hydrogen-2 (deuterium), ‎and Hydrogen-3 (tritium).
