Radioactive Isotopes-FAQs

1. What is meant by Radioactive Isotopes?

Radioactive Isotopes are also called radioisotope, they are isotopes of the elements that shows radioactivity.

2. What are 4 Examples of Radioactive Isotopes?

Four examples of radoactive isotopes are,

• Carbon-14
• Strontium-85
• Nickel-63
• Iodine-131

3. What is Radioactivity?

Radioactivity is the property of element that allows some nucleus with higher number of neutrons to emeit alpha, beta, and gamma rays. The isotopes that shows radioactivity are called radioactive isotopes.

4. What are the Three Types of Radioactivity?

The three types of radioactivity are,

• Alpha Decay
• Beta Decay
• Gamma Rays

5. Is Uranium-235 a Radioisotope?

Uranium-235 (U-235) is the radioactive isotopes of the element Uranium. In nucleus of Uranium it have 92 Protons, and 143 Neutrons.

6. Which substance was the first to be detected radioactive?

Uranium was the first radioactive substance to be detected. It has three isotopes, U-238 (most abundant), U-235, U-234.

7. Which Isotope of Carbon is used in Carbon Dating?

Carbon-14 is used in carbon dating as it is the radioactive isotope of carbon. Carbon has three naturally occurring isotopes C-12, C-13, C-14.

8. What are Uses of Radioactive Isotopes?

Radioactive Isotopes have various uses and some of its uses are,

• Radioactive isotopes are used in medice
• Radioactive isotopes are used in industries.
• Radioactive isotopes is used to for carbon-14 dating, etc.

Radioactive Isotopes or Radioisotopes are the isotopes of the elements that are not stable, i.e. they emit some radiation and change the composition of their nucleus. Radioactive isotopes are defined as the isotopes of any chemical element that have different masses and unstable nuclei and release energy by spontaneously emitting radiation in the form of alpha rays, beta rays, and gamma rays. This property of some nuclei to emit energy as alpha, beta, and gamma rays is called radioactivity, and the isotopes of the elements that show radioactivity are called radioisotopes or radioactive isotopes.

In this article, we will learn about Isotope definition, Radioactive Isotopes, Uses of Radioactive Isotopes, and others in detail.
