What are isotopes used example?
What are isotopes used example?
For example, hydrogen, the lightest element, has three isotopes with mass numbers 1, 2, and 3. Only hydrogen-3 (tritium), however, is a radioactive isotope, the other two being stable….How are radioactive isotopes used in medicine?
| isotope | half-life (years, unless noted) |
|---|---|
| 236U | 2.342 × 107 |
| 237U | 6.75 days |
| 238U | 4.468 × 109 |
What are the uses of isotopes Class 9?
An isotope of uranium is used as fuel in nuclear reactor. An isotope of cobalt is used in treatment of cancer. An isotope of iodine is used in treatment of goitre.
What are radioactive isotopes give two examples Class 9?
The radiations emitted are in the form of alpha particles, beta particles and gamma rays. Common examples of radioactive isotopes are Arsenic−74, Iodine−131 and Cobalt−60.
What are the 5 uses for isotopes?
Radioactive isotopes find uses in agriculture, food industry, pest control, archeology and medicine. Radiocarbon dating, which measures the age of carbon-bearing items, uses a radioactive isotope known as carbon-14. In medicine, gamma rays emitted by radioactive elements are used to detect tumors inside the human body.
What are isotopes class 10th?
Isotopes are two or more forms of the same element that contain an equal number of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.
What are isotopes Class 9 answer?
Isotopes are atoms of same element having same atomic number but different mass numbers.
What are radioisotopes Class 10 ICSE?
Solution. Artificial radioactive substances can be produced by bombarding lighter nuclides with alpha particles, protons and neutron. The radioactive substances produces in this manner are called radioisotopes.
What is isotope and give 5 example?
Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). Such isotopes are commonly referred to as stable nuclides or stable isotopes.
