Question

Select every statement that is true about radioactivity (more than one may be selected):

a. Gamma decay is a helium nucleus being emitted from the nucleus of a larger atom.

b. Beta decay is a neutron in the nucleus of an atom splitting into a proton, which stays in the nucleus, and an electron, which is ejected.

c. The products of a decay reaction are often themselves radioactive.

d. Different isotopes of the same element often react differently in radioactive decay processes.
