Homework question over nuclear change, please help.?

Raleigh Lufkin: The nuclear change involves either beta radiation or alpha radiation.In beta radiation, a neutron disintegrates into a proton and an electron. The electron is ejected from the atomic nucleus while the newly formed proton stays. The process is known as beta decay (i.e. a type of radioactive decay) and the emitted electron is known as a beta particle. In the end, the number of protons increases by one. In alpha radiation, a helium nucleus (two protons and two neutrons as a single unit) is ejected from the original atomic nucleus. The process is known as alpha decay (i.e. a type of radioactive decay) and the emitted helium nucleus is known as a alpha particle. In the end, the number of protons decreases by two.
