Radioactive Decay
Study online at https://quizlet.com/_acmqzz
1. ⁴₂He alpha particle
2. beta particle the particle formed by changing a neutron to a proton
3. gamma rays high energy rays & a type of electromagnetic radiation
4. Beta- particle symbol β⁻
5. Gamma symbol γ
6. Alpha Decay Mass number decreases by 4 (loss of 2 protons and 2
neutrons); Atomic number decreases by 2 - emits a helium
nucleus

7. Half life the amount of time it takes the nuclei of radioactive isotope
to decay
8. alpha particle a positively charged particle consisting of two protons and
two neutrons
9. fission a nuclear reaction in which a massive nucleus splits into
smaller nuclei with the simultaneous release of energy
10. fusion a nuclear reaction in which nuclei combine to form more
massive nuclei with the simultaneous release of energy
