What is the balanced nuclear equation for the alpha decay of plutonium-238?(a) (b) (c) (d)

Isotope A decays to isotope E through the following series of steps, in which the products of the individual decay events are themselves radioactive and undergo further decay until a stable nucleus is ultimately reached. Two kinds of processes are represented, one by the shorter arrows pointing right and the other by the longer arrows pointing left. (b) Identify and write the symbol for each isotope in the series:

Which of the following is the correct nuclear equation for the alpha decay of Th-227?

In alpha decay, which particle is emitted from the nucleus of an unstable atom?

Which nuclide is produced when uranium-238 undergoes alpha decay?

Which of the following symbols represents an alpha particle?
