Bismuth Isotopes - List and Properties (2024)

FAQs

What are the isotopes of bismuth? ›

Besides ²⁰⁹Bi, the most stable bismuth radioisotopes are ^210mBi with a half-life of 3.04 million years, ²⁰⁸Bi with a half-life of 368,000 years and ²⁰⁷Bi, with a half-life of 32.9 years, none of which occurs in nature. All other isotopes have half-lives under 1 year, most under a day.

Due to its hugely long half-life, for nearly all applications ²⁰⁹Bi can be treated as non-radioactive.

Bismuth-213 was the first reported alpha-particle emitter used in a clinical trial as a potential cancer therapeutic. This radionuclide has a half-life of 45.6 min and mostly decays to become the alpha emitter polonium-213, via a branched scheme.

Three naturally existing isotopes of hydrogen are tritium, deuterium, and protium. Each isotope comprehends of unique properties.

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining Bismuth-210 transforms into another atom (polonium-210 in this case) each day. If you begin with 100 mg of Bismuth-210, how much remains after one week?

Bismuth finds its main uses in pharmaceuticals, atomic fire alarms and sprinkler systems, solders and other alloys and pigments for cosmetics, glass and ceramics.

Bismuth was long considered to be the heaviest stable element in the periodic table. However, in 2003, scientists discovered that it is weakly radioactive: bismuth-209 (its only primordial isotope) has a half-life more than a billion times longer than the estimated age of the universe.

Bismuth is brittle and has a very low melting point of 271.5°C, explaining all of it's weaknesses and ineffectivenesses: Ineffective and weak against ground: due to it's brittleness it will shatter when hitting something stationary at high speed. Ineffective and weak against fire: it will melt as soon as it heats up.

Bismuth-210 decays to polonium-210 through a beta decay. One of the most common places for polonium to concentrate in nature is in tobacco. As the radium in the soil decays, the electrically charged polonium ion adheres to dust particles that accumulate on the hairy underside of tobacco leaves.

What does bismuth react badly with? ›

At red heat, bismuth reacts with steam, but it is not affected by cold, air-free water; it combines directly with sulfur and with the halogens (fluorine, chlorine, bromine, iodine).

Bismuth is used in making chemical alloys, medicine, and transistors. A 10-mg sample of bismuth-214 decays to 9 mg in 3 min.

Bismuth is stable to oxygen and water but dissolves in concentrated nitric air.

Abstract. The only naturally occurring isotope of bismuth, 209Bi, is commonly regarded as the heaviest stable isotope.

Once thought to be the heaviest stable isotope to exist in nature, experiments conducted in 2002 showed that bismuth-209 is unstable and decays into thallium-205 through alpha decay.

Bismuth is used in making chemical alloys, medicine, and transistors. A 10-mg sample of bismuth-214 decays to 9 mg in 3 min.

There are 7 known isotopes of Hydrogen. It was the first element to form when the universe began, and is used as fuel to create light in stars through nuclear fusion. Beryllium is an alkaline-earth metal known for being strong and lightweight. With atomic numbor 4, it has 12 known isotopos, I stablo and 11 exotic.
