What happens to atoms that are radioactive? The nuclei decay or react by emitting alpha or beta particles. What is the role of isotopes in radiometric dating? A radioactive isotope decays into its stable daughter product at a constant rate.

What happens to an atom during radioactive decay quizlet?

The atomic nuclei of radioactive isotopes release fast-moving particles and energy. This changes the identity of the atom to a different element by changing the atomic number in its nucleus.

What does a radioactive element do quizlet?

Radioactive elements can be used to destroy unhealthy cells like cancer cells in the process of radiation therapy. Adding the number of protons and the number neutrons found in the nucleus of an atom yields the mass number for the isotope. A tracer can be used by doctors and industries to diagnose problems.

Which process occurs during radioactive decay quizlet?

What occurs during radioactive decay? Unstable isotopes release charged particles.

What is radioactive quizlet?

Radioactivity. The process by which an unstable nucleus emits one or more particles or energy in the form of electromagnetic radiation. Nuclear Radiation. The particles that are released from the nucleus during radioactive decay. You just studied 13 terms!

What happens to atoms during radioactive decay?

When radioactive atoms decay, they release energy in the form of ionizing radiation (alpha particles, beta particles and/or gamma rays). The energy is called ionizing radiation because it has enough energy to knock tightly bound electrons from an atom's orbit. This causes the atom to become a charged ion.

What happens during radioactive decay during radioactive decay?

Elements that emit ionizing radiation are called radionuclides. When it decays, a radionuclide transforms into a different atom – a decay product. The atoms keep transforming to new decay products until they reach a stable state and are no longer radioactive.

What does it mean when an element is radioactive?

Radioactive elements are made up of atoms whose nuclei are unstable and give off atomic radiation as part of a process of attaining stability. The emission of radiation transforms radioactive atoms into another chemical element, which may be stable or may be radioactive such that it undergoes further decay.

How are radioactive elements used for medical diagnosis quizlet?

How are radioactive elements used for medical diagnosis? The elements are placed in special cameras which record images from emitted radiation, like x-ray equipment. The radiation from certain elements can penetrate the entire body and expose all internal organs to photographic film.

What happens during radioactive decay geology quizlet?

What happens during radioactive decay? Parent isotopes turn into daughter isotopes. What is the scientific definition of half-life? Two containers hold the same radioactive isotope.
