Currently covering basic radioactive decay in a lecture and I get it but the charges don't make any sense to me;
Alpha radiation emits a He nucleus (2+) but the charges of the other species don't change
U(238/92) --> Th(234/90) + He(4/2)
And beta radiation, neutron (0) --> proton (+) and electron emitted leaving Nitrogen positively charged
C(14/6) --> N(14/7) + e(0/-1)
Really confused, is it just due to the charges just not being written into these equations any where including text books, or am I missing something?
What should I do?
