Question: What Are The Characteristics Of Isotopes?

What are the different types of radioactive isotopes?

But in the process, several types of radioactive atoms are generated.

This is called a decay chain.

When uranium-238 decays, it produces several isotopes of: Thorium….There are four types of radiation given off by radioactive atoms:Alpha particles.Beta particles.Gamma rays.Neutrons..

What are 3 examples of isotopes?

Isotopes ExamplesCarbon-14. A naturally occurring radioactive isotope of carbon having six protons and eight neutrons in the nucleus. … Iodine-131. It is an isotope because it contains a different number of neutrons from the element iodine. … Tritium.

What are isotopes used for?

Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.

Why do isotopes occur?

Isotopes are atoms of the same element with different masses. They get these different masses by having different numbers of neutrons in their nucleii. … When an unstable isotope decays, it makes a new atom of a different element.

What is the most radioactive isotope?

PoloniumIsotopes. Polonium has 42 known isotopes, all of which are radioactive. They have atomic masses that range from 186 to 227 u. Po (half-life 138.376 days) is the most widely available and is made via neutron capture by natural bismuth.

What are some characteristics of radioactive isotopes?

Each radioisotope has a characteristic disintegration or semi-life period. Energy may be liberated mostly in the form of alpha (helium nuclei), beta, (electrons or positrons), or gamma (electromagnetic energy) rays. Several unstable and artificial radioactive isotopes have medical uses.

Which properties of the isotopes are similar?

Isotopes of the same element have different physical properties (melting points, boiling points) and the nuclei of some isotopes are unstable and radioactive.

What are 4 uses of radioactive isotopes?

Why are some isotopes Radioactive?

Many elements have one or more isotopes that are radioactive. These isotopes are called radioisotopes. Their nuclei are unstable, so they break down, or decay, and emit radiation. … A: The nucleus may be unstable because it has too many protons or an unstable ratio of protons to neutrons.

Do isotopes have different properties?

Atoms of the same element that differ in their numbers of neutrons are called isotopes. … Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties. That’s because they have the same numbers of protons and electrons.

How do you identify a radioactive isotope?

Radioactive isotopes are detected by:photographic film.a cloud or bubble chamber.a liquid scintillation detector.a Geiger-Muller counter.
