. 2) Uranium, Radium, Polonium
What are isotopes and give its application?
Some isotopes have unstable atomic nuclei that undergo
radioactive decay
. These isotopes are radioactive in nature and are, therefore, known as radioisotopes (or radionuclides). Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238.
What are the five applications of isotopes?
Cobalt-60 is the isotope of choice for radiotherapy
. Phosphorus-30 is used in the treatment of leukemia or blood cancer. Iodine-131 radioisotope, used as a ‘tracer', is injected into the body to check the activity of the thyroid gland.
What are the three applications of isotopes?
- Uranium-235 is used for nuclear fission and as a fuel in nuclear reactors.
- An isotope of cobalt is used in the treatment of cancer.
- An isotope of iodine is used in the treatment of goiter.
What are the applications of isotopes?
1) Some isotopes are
used for solving chemical and medical mysteries
. 2) Isotopes are also commonly used in the laboratory to investigate the steps of a chemical reaction. 3) The isotopes of uranium is used as a fuel in nuclear reactors. 4) The isotope of iodine is used in the treatment of goitre.
What are the applications of isotopes Class 9?
- An isotope Uranium is used as a fuel in nuclear reactor.
- An isotope of cobalt is used in treatment of cancer.
- An isotope of iodine is used in treatment of goitre.
How do we use isotopes in everyday life?
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 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. Every chemical element has one or more isotopes.
How are isotopes used in medicine?
Nuclear medicine uses radioactive isotopes in a variety of ways. One of the more common uses is as
a tracer in which a radioisotope
, such as technetium-99m, is taken orally or is injected or is inhaled into the body. … Therapeutic applications of radioisotopes typically are intended to destroy the targeted cells.
How many different types of isotopes are there?
Isotope Facts
All elements have isotopes. There are
two main types
of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes.
What are the isotopes Class 9?
Isotopes are
the atoms in which the number of neutrons differs and the number of protons is the same
. From the above definition of atomic mass and the atomic number, we can conclude that isotopes are those elements having the same atomic number and different mass number.
Why are isotopes important in everyday life?
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.
How are isotopes used in industry?
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 is an isotope in your own words?
An isotope of a chemical element is
an atom that has a different number of neutrons
(that is, a greater or lesser atomic mass) than the standard for that element. The atomic number is the number of protons in an atom's nucleus.
What is isotope give example?
The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number. For example,
carbon-12
, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.
What is the isotope symbol?
Isotope Notation
Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and
E
is the element symbol. The mass number “A” is indicated with a superscript to the left of the chemical symbol “E” while the atomic number “Z” is indicated with a subscript.
