Term radioactive decay	Definition the atomic nuclei of unstable isotope release fast-moving particles and energy
Term tracer	Definition radioactive isotopes that can be followed through the steps of a chemical reaction or an industrial process.

What is happening to the unstable atoms that are going through the process of radioactive decay?

As unstable atoms decay and attempt to become stable, the nuclei release energy in the form of ionizing radiation (alpha particles, beta particles and gamma rays). The energy released is called ionizing radiation because it has enough energy to knock tightly bound electrons from the atom’s orbit.

What occurs during radioactive decay?

Radioactive decay is the process in which the nuclei of radioactive atoms emit charged particles and energy, which are called by the general term radiation. Radioactive atoms have unstable nuclei, and when the nuclei emit radiation, they become more stable.

What are the industrial uses of radioactive isotopes?

Industrial tracers Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment. Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.

What can be followed through the steps of a chemical reaction?

Radioactive isotopes that can be followed through the steps of a chemical reaction or an industrial process. Radioactive isotopes can be go through the same process as nonradioactive isotopes but will leave traces of radiation behind which can later be detected.

What are some examples of radioactive dating?

Parent	Daughter	Dating Range(years)
Uranium-238	Lead-206	10 – 4,600 million
Potassium-40	Argon-40	0.05 to 4,600 million
Rubidium-87	Strontium-87	10 – 4,600 million
Carbon-14	Nitrogen-14	100- 70,000 years

Which of the following particles can be ejected from an atom during radioactive decay?

Radioactivity can be ejected particles or very energetic photons (strong electromagnetic radiation called “Gamma rays”). As the elements get heavier more neutrons become necessary to make their nuclei stable.

How does an unstable atom become stable?

Radiation is emitted from atoms when an unstable atom decays to become more stable. When an atom has extra neutrons or protons, it causes the element to become unstable. This activity helps students understand how emitting an alpha or beta particle changes the structure of an atom.

What is the radioactive process?

Radioactivity is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation, As each nucleus disintegrates, in its effort to find a more stable combination, it emits a charged particle that, because of its kinetic energy, is capable of penetrating solid material.

How Can radiation be used in industry?

There are many industrial uses of radioactive materials, including material density evaluation, product sterilization, quality control, static elimination, and electricity generation.

What are the isotopes used in industry?

One of the important applications of isotopes in industry is radiography. The isotopes most commonly used for radiographic testing of such products as castings and welds are cobalt 60, cesium 137, and iridium 192. material.

What are the 4 types of chemical reactions?

Four basic types Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.

What do you need to know about chemical reactions?

In learning about chemical reactions students will need to describe various substances, which at this level will be materials they are familiar with (the kitchen and changes involving cooking are very good starting points).

Where does the new material in a chemical reaction come from?

Any new materials come from the reacting substances. Changes that may accompany a chemical reaction include colour, appearance and production of new materials, for example, a gas. Mixing alone may not cause a chemical reaction to take place.

How are chemical reactions similar to other processes?

Processes like cordial mixing with water, the use of colouring in food, freezing and boiling are seen as similar to chemical changes like those involved in cooking eggs. In combustion, children frequently believe materials like wood or paper just disappear – after all there is not much of the product left to see.

Is it necessary for mixing to cause a chemical reaction?

Mixing alone may not cause a chemical reaction to take place. While heat is often necessary to initiate a chemical reaction it is not always necessary. Chemical reactions are used to produce most of our energy.
