What is an isotope easy definition?
Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.
What are isotopes Class 9?
Isotopes: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, isotopes are elements with the same atomic number but different mass numbers.
What are the 3 types of isotopes?
Hydrogen and its two naturally occurring isotopes, deuterium and tritium. All three have the same number of protons (labeled p+) but different numbers of neutrons (labeled n). A family of people often consists of related but not identical individuals. Elements have families as well, known as isotopes.
What are isotopes explain with example?
Isotopes are atoms of the same element having same atomic number but different mass numbers. Examples: All chlorine atoms contains 17 protons but some chlorine atoms contain 18 neutrons whereas the other one contains 20 neutrons. Therefore,Chorine has two isotopes of mass number 35 and 37.
Are isotopes important?
Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.
What is another word for isotope?

What are the applications of isotopes Class 9?
Uses of Isotopes:
Even fossil’s age can be determined by using this technology. 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 the applications of isotope?
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.
What is difference between isotopes and isobars?
Isobars are those elements which have a different atomic number but the same mass number. Isotopes are the atoms in which the number of neutrons differs and the number of protons is the same. Isotopes are those elements having the same atomic number and different mass number.
How do humans use 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.
How do we use isotopes in everyday life?
|99mTc*||brain, thyroid, liver, bone marrow, lung, heart, and intestinal scanning; blood volume determination|
|131I||diagnosis and treatment of thyroid function|
|198Au||liver disease diagnosis|
Why do isotopes occur?
Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactors.
How do you identify isotopes?
Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons).
Which of the following is an example of isotope?
For example, an isotope with 6 protons and 6 neutrons is carbon-12 or C-12. An isotope with 6 protons and 7 neutrons is carbon-13 or C-16. Note the mass number of two isotopes may be the same, even though they are different elements. For example, you could have carbon-14 and nitrogen-14.
What are isotopes answer?
Isotopes are versions of the same element. They have the same number of protons and electrons as the element but different mass numbers and number of neutrons.
