What is the alpha decay of bismuth 213?
Decay Properties of 225Ac and 213Bi. Ac is the parent radionuclide of 213Bi and is a relatively long-lived α-emitter with a half-life of 9.9 d. It decays via a cascade of six short-lived radionuclide daughters to stable 209Bi with four net alpha particles emitted per decay (Figure 2).
What is the alpha decay of bismuth?
Bismuth-209 (209Bi) is the isotope of bismuth with the longest known half-life of any radioisotope that undergoes α-decay (alpha decay). It has 83 protons and a magic number of 126 neutrons, and an atomic mass of 208.9803987 amu (atomic mass units). Primordial bismuth consists entirely of this isotope.
What is the alpha decay of bismuth 212?
Bi-212 undergoes beta decay to Po-212 (64.07(7)%), and alpha decay to Tl-208 (35.93(7)%).
What is the alpha decay of bismuth 210?
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.
When the isotope bismuth-213 emits an alpha particle what new element results?
Explanation of Solution If the one alpha particle emits from Bi-213, then the atomic number becomes 81 due to reduction of two unit in atomic number and atomic mass number becomes 209 due to reduction of four units in the atomic mass number. The atomic number of new element becomes 81 and mass number becomes 209.

What does bismuth decay into?
thallium
However, in 2003, researchers at the Institut d’Astrophysique Spatiale in Orsay, France, found that bismuth does decay into thallium, but it has an extremely long half-life: about 20 billion billion years (That’s 20 followed by 18 zeroes).
Is bismuth 213 stable?
Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.98040(1).
Is it impossible for the alpha decay of bismuth-212 to produce the same element as the beta decay of bismuth-212?
The symbol below represents an alpha particle. (i) The equation below represents the alpha decay of bismuth-212. Complete the equation by writing the correct number in each of the two boxes. (ii) It is impossible for the alpha decay of bismuth-212 to produce the same element as the beta decay of bismuth-212.
When the isotope bismuth 213 emits an alpha particle what new element results?
How many protons does bismuth 213 have?
Why does alpha result in the greatest change in atomic number?
All isotopes have the same number of protons, but different number of neutrons. 55. Because it has twice as much charge as a beta particle, an alpha particle interacts more strongly with atomic electrons and loses energy more rapidly by ionizing the atoms.
Is bismuth-213 stable?
What is the alpha decay of PA 231?
actinium-227
Protactinium’s most stable isotope, protactinium-231, has a half-life of about 32,760 years. It decays into actinium-227 through alpha decay.
