When uranium-238 undergoes alpha decay, it emits an alpha particle and forms which new nucleus?

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

Which of the following symbols represents an alpha particle?

An unstable nucleus releases radiation in the form of a helium particle. What process is occurring?

When the isotope actinium-227 (227 89 Ac) undergoes alpha decay, what is the resulting nucleus?

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:
