Question #fab75

Answer 1

Iodine-125 undergoes electron capture decay.

`""_53^125"I" + ""_text(-1)^0beta -> ""_52^125"Te"`

This is because an electron changes the proton to one less so Iodine which has an atomic number of 53 will change to atomic number 52, which is Te. And of course the mass number doesn't change.

Hope I helped :)
