Will PB 206 undergo beta decay?
The instability caused by the alpha decay is corrected by the eventual beta decay, leading to the stable nucleus of lead 206, with its 82 protons and 124 neutrons.
What does lead decay into?
Lead is not radioactive, and so does not spontaneously decay into lighter elements. Radioactive elements heavier than lead undergo a series of decays, each time changing from a heavier element to a lighter or more stable one. Once the element decays into lead, though, the process stops.
What is the daughter isotope product when lead Pb undergoes beta decay?
21483 Bi
Choice D is correct, the daughter isotope is 21483 Bi.
What kind of decay does lead 210 undergo?
The method has been applied to the ores of uranium. In the series of unstable products from the radioactive decay of uranium-238, lead-210 results from the decay of radon-222 and is a precursor of the stable isotope lead-206.
What does the 208 in lead-208 represent?
The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay chain, the neptunium series, terminates with the thallium isotope 205Tl.
How is lead-210 used?
Lead-210, an unstable (radioactive) isotope of Pb, has in the last few decades been widely used for dating environmental records in lake sediments and peat bogs13, for tracing soil erosion within a catchment, and assessing sediment distribution within a lake basin (cf14,15).
What happens in B decay?
Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +.
Where does the lead 210 Pb come from?
Lead 210Pb is a naturally occurring radioactive nuclide element of the uranium (238U) radioactive series. It is produced as a result of the decay of so-called short-lived progeny of 222 Rn, which comes from the decay of 214 Po (99.98%) and 214 Bi by 219 Tl (0.02%). 210Pb is subject to beta decay into 210Bi.
What kind of radiation is emitted from Lead 210?
During the decay of the atom of lead 210, beta and gamma radiation is emitted. As mentioned above, the state of secular radioactive equilibrium of lead and polonium, which is the emitter of alpha radiation, is relatively quick to define.
What is the half life of 210Pb radioisotope?
A shorter-lived naturally occurring radioisotope, 210Pb with a half-life of 22.3 years, is useful for studying the sedimentation chronology of environmental samples on time scales shorter than 100 years.
What are the names of the isotopes of lead?
The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay chain, the neptunium series, terminates with the thallium isotope 205Tl.
