Writing Nuclear Equations

Write nuclear equations for

(a) mercury-201 undergoing electron capture; (b) thorium-231 decaying to protactinium-231.

The radioactive decay of thorium-232 occurs in multiple steps, called a radioactive decay chain The second product produced in this chain is actinium-228. Which of the following processes could lead to this product starting with thorium-232?

(a) Alpha decay followed by beta emission, (b) Beta emission followed by electron capture, (c) Positron emission followed by alpha decay, (d) Electron capture followed by positron emission

s

(e) More than one of the above is consistent with the observed transformation
