What happens when polonium undergoes alpha decay?
What happens when polonium undergoes alpha decay?
Alpha decay of polonium will always produce a lead isotope as the daughter isotope because the loss of two protons changes the atom’s atomic number from 84 to 82. The mass number of the isotope also decreases by four because there are four nuclear particles in the ejected alpha particle.
Which product is made from the alpha decay of polonium 208?
Knowing that polonium is element 84 and helium is element 2, we can easily determine that the result must be element 82, lead. And since polonium-208 emits a nucleus with an atomic mass of 4, the resulting atom must be lead-204.
What is the alpha decay of lead 208?
Polonium-212 undergoes alpha decay to produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles.
Does polonium undergo alpha decay?
alpha decay Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).
How to write a balanced equation for polonium-208?
EXAMPLE Write a balanced nuclear equation for the α decay of polonium-208. Solution The unbalanced equation is “”_84^208″Po” → “”_2^4″He” + “X” The superscript of “X” must be 208 – 4 = 204. The subscript of “X” must be 84 – 2 = 82. Element 82 is Pb.
What is the half life of polonium 210?
not present Isotope H Half-Life S Specific Activity (TBq/g) D Decay Mode A Alpha (α) Energy (MeV) P Polonium-208 2 2.9 yr 2 21.8 α 5 5.1 P Polonium-209 1 103 yr 0 0.63 α 4 4.9 P Polonium-210 1 138 days 1 166 α 5 5.3
Which is the daughter isotope of polonium in alpha decay?
The isotope before decay occurs is called the parent isotope, while the isotope after the decay process is called the daughter isotope. Alpha decay of polonium will always produce a lead isotope as the daughter isotope because the loss of two protons changes the atom’s atomic number from 84 to 82.
What kind of radiation is produced by polonium 212?
Alpha radiation. Polonium-212 undergoes alpha decay to produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles. An alpha particle, α, is simply the nucleus of a helium-4 atom, which means that it contains
