Write the nuclear equations for the following radioactive processes. An atom produces alpha and gamma radiation as it decays into nihonium-289.

Write the equation for the beta-minus decay of phosphorus-32.

Please provide an equation for the following nuclear process: 231Pa decays via ß-emission.

Write a nuclear equation for the decay of Polonium-211.

A tiny percent of all naturally-occurring carbon atoms on Earth are carbon-14. Trees (and all living things) incorporate C-14 into their bodies when alive, but this ceases at death, after which the amount of C-14 present gradually decreases due to nuclear decay. Wooden artifacts from long ago can be dated by the percent of carbon-14 remaining in them. A sample of a wooden object from an archaeological site contains only 12.5% of the level of carbon-14 expected for a live tree. How many half-lives have passed since that piece of wood was a living tree?
