What are 3 examples of isotopes? For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.
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. … An atom is first identified and labeled according to the number of protons in its nucleus.
What are 2 examples of isotopes?
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 3 uses of radioactive isotopes?
Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and metabolism.
What are 5 examples of isotopes?
Isotopes Examples
- Carbon-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 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. Atomic mass adds to that the number of neutrons in the nucleus.
What are isotopes give an example?
Isotopes: the atoms of the same element which have the same atomic number Z but differ in their mass number A are called isotopes. Example: Hydrogen has three isotopes ( 1 1 H , X 1 1 X 2 1 2 1 H , X 1 3 X 2 1 2 3 H ) , Protium, Deuterium, Tritium.
What is isotopes very short answer?
Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. In other words, isotopes are variants of elements that differ in their nucleon numbers due to a difference in the total number of neutrons in their respective nuclei.
What is isotopes and its examples?
Isotope → Isotopes are atoms with the same number of protons, but differ in numbers of neutrons. Isotopes are different forms of a single element. Example – Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons.
How do you identify an isotope?
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).
Can isotopes be created?
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 we use isotopes in everyday life?
Among such prevalent uses and applications of radioisotopes are, in smoke detectors; to detect flaws in steel sections used for bridge and jet airliner construction; to check the integrities of welds on pipes (such as the Alaska pipeline), tanks, and structures such as jet engines; in equipment used to gauge thickness …
How are isotopes important?
Radioactive isotopes differ in the stability of their nuclei. Measuring the speed of decay allows scientists to date archaeological finds, and even the universe itself. Stable isotopes can be used to give a record of climate change. Isotopes are also commonly used in medical imaging and cancer treatment.
What are the applications of radioactive isotopes?
Applications have played significant role in improving the quality of human life. The application of radioisotopes in tracing, radiography, food preservation and sterilization, eradication of insects and pests, medical diagnosis and therapy, and new variety of crops in agricultural field is briefly described.
What are some real life examples of isotopes used?
Among such prevalent uses and applications of radioisotopes are, in smoke detectors; to detect flaws in steel sections used for bridge and jet airliner construction; to check the integrities of welds on pipes (such as the Alaska pipeline), tanks, and structures such as jet engines; in equipment used to gauge thickness …
What is the symbol of an isotope?
To write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol. The symbols for the two naturally occurring isotopes of chlorine are written as follows: 3517Cl and 3717Cl.

How do we use isotopes?
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.
How do isotopes work?
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
What is isotopes class 10th?
Ans: Isotopes are atoms of different masses of the same element. By having different numbers of neutrons in their nuclei they get these different masses. However, they are the same type of atom, because they have the same number of protons in their nuclei.
What are isotopes give 2 examples?
The examples of radioactive isotopes are uranium- 235 and uranium- 238. Some other examples of isotopes are carbon -12, Carbon -13 and carbon -14. In this example the numbers 12,13 and 14 represent the number of neutrons.
What are some examples of isotopes?
Isotope Examples
Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth’s crust. Both have long half-lives.
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. … The number indicates the isotope’s mass number.
