(adsbygoogle = window.adsbygoogle || []).push({}); 1. hi i would like to now how i could do this?

the question says:

iodine-131 is a radiactive element used in the medical diagnosis and treatment of thyroid problems. iodine-131 undergoes simultaneous beta and gamma decay and has a half-life of 8.00 days.

2.im ask to write the complete decay equation for iodine-131

3. i know the formula for the life time is N=No(1/2)^n and n=time after/half-life...T(1/2)

but im not sure if thats the equation to do the decay...

...or the complete decay equation they are asking for is a series of radioactive elements.. like the folowing

ex: 226 Ra--->222 Rn + 4 He

....... 88.............86..........2

if is as the example im not sure how to do it..could someone explain me how could i do it ? thanks
