How many `alpha` and `beta` particles will be emitted by an element `84^(A^(218))` is changing to a stable isotope of `82^(B^(206))`

Calculate the number of alpha and beta particles emitted in the conversion of 90^(Th^(232) to 82^(pb^(208)) .

92^(U^(238)) undergoes a series of changes by emitting alpha and beta particles and finally 82^(pb^(206)) is formed. Calculate the number of and particles emitted during the change.

The atomic mass of Th is 232 and its atomic number is 90. In terms of its radioactivity six alpha and four beta particles are emitted. What is the mass number and atomic number of the product.

Mass number of a radioactive element is 232 and its atomic number is 90. When this element undergoes certain nuclear reactions, it transforms into an isotope of lead with a mass number 208 and an atomic number 82. Determine the number of alpha and beta dacay that can occur.

(Bi)_212^83 can disintegrate either by emitting an alpha -particle or by emitting a beta -particle. (a) write the two equations showing the products of the decays. (b) The probabilities of disintergration by alpha and beta -decays are in the ratio 7/13. The overall half-life of Bi^212 is one hour. If 1 g pure Bi^212 is taken at 12.00 noon,what will be the composition of this sample at 1 p.m the same day?
