What pathway would decay polonium-218 to bismuth-214?
Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.
What particle is emitted when lead-214 21482Pb undergoes natural radioactive decay to bismuth-214 21483Bi?
Lead-214 undergoes beta decay to form Bismuth-214. In beta decay, a neutron is converted into a proton, emitting an electron and an antineutrino.
What is 417 degrees f in centigrade?
417 degrees Fahrenheit is equal to approximately 214 degrees Celsius.
Does uranium decay to lead in one step?
No, it's a long chain. The decay sequence is: Uranium-238 to thorium-234 to protactinium-234 to Uranium-234 to thorium-230 to radium-226 to radon-222 to polonium-218 to lead-214 to bismuth-214 to polonium-214 to lead-210 to bismuth-210 to polonium-210 to lead-206 which is its final stable form. Radioactive decay occurs when an unstable (radioactive) isotope transforms to a more stable isotope, generally by emitting a subatomic particle such as an alpha or beta particle (helium nucleus or electron). The half-life of one of the elements above can be shorter than a millisecond (Po-214) or as long as 4.5 billion years (U-238).
How many atom of a 1.0 mole sample of bismuth 214 will remain after 20 minutes?
All radio active reactions are of first order reactions , for those first order reactions rate constant , k = 0.693 / t 1/2 : t 1/2 = half life of Bi is = 19.7 min So k = 0.693 / 19.7 = 0.0352 min -1 For a first order reaction rate constant , K = ( 2.303/t)x log (a / ( a-x) ) Where a = initial atoms = 6.023x10 23 atom / mol a-x = atoms left after time t = ? t = time = 20 min Plug the values we get log (a / ( a-x) = kt / 2.303 = ( 0.0352x20 ) / 2.303 = 0.305 a / (a-x) = 10 0.305 = 2.02 (a-x) = (6.023x10 23 ) / 2.02 = 2.98 x 10 23 atoms
