Hi Nancy and whoever can help,

I have a question regarding chem #113, the question mentioned beta decay. However, there are 2 types of beta decays, beta - decay and beta + decay, or beta emission and positron emission. So on DAT, if they used just beta decay, do we automatically assume it's the the beta- decay? Or am I missing something here 🙂

Thanks again! 😀

Also, for number 118 b), it's wrong because it is only likely to be coloured instread of expected? Just a wording thing? Thanks again!

In a beta decay.....a beta particle { electron } is emitted. The DAT will not confuse you with any terminology beyond that. Thus, yes......ALWAYS assume a beta decay gives a beta particle.

Hope this helps..keep studying, no easy way out, your hard work will pay off.
