Across
- 2. A process in which an unstable nucleus emits gamma radiation (high-energy photons) without changing its atomic number or mass number.
- 5. The process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy, as seen in stars.
- 6. A technique used to determine the age of materials, such as rocks or fossils, by measuring the amount of radioactive isotopes present and their decay rates.
- 9. The time required for half of the radioactive nuclei in a sample to decay, a key concept in understanding radioactive decay and calculations related to it.
Down
- 1. The process by which unstable atomic nuclei lose energy by emitting radiation, resulting in the transformation of an element into another.
- 3. The central part of an atom, containing protons and neutrons, which plays a crucial role in nuclear reactions and radioactivity.
- 4. The process of splitting a large atomic nucleus into smaller nuclei, accompanied by the release of energy, commonly used in nuclear reactors.
- 7. A type of radioactive decay in which an atomic nucleus emits an alpha particle (two protons and two neutrons), resulting in a new element with a lower atomic number.
- 8. A form of radioactive decay in which a neutron is transformed into a proton, emitting a beta particle (electron or positron) and increasing the atomic number of the element.
