I need to complete the following sentence. If I think that electron capture or alpha decay does not occur in my decay process, I have to type a '0' (zero) in the appropriate box:
Converting an atom of the isotope Uranium (238-92) into an atom of thorium can be accomplished if an electron capture process occurs___times and an alpha decay occurs ___times. The resulting isotope has a mass number___ and an atomic number___ .
Initially I thought the right answers were: zero, one, 234, 90. But after I realized that I cannot say one times because times is plural. Is it only one right answer of there are different options? The resulting isotope has definitely a atomic number of 90, but I am not sure about the rest. Thanks for your help
