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 isotopes kid definition?
An isotope is one of two or more types of atoms of a chemical element with the same number of protons but with different numbers of neutrons and therefore different atomic masses . ... The isotopes of an element occupy the same position in the periodic table.
What are isotopes for dummies?
Atoms in a chemical element that have different numbers of neutrons than protons and electrons are called isotopes. The atoms in a particular element have an identical number of protons and electrons but can have varying numbers of neutrons.
What is an isotope simple example?
The definition of an isotope is an element with similar chemical make-up and the same atomic number, but different atomic weights to another or others. An example of an isotope is Carbon 12 to Carbon 13 . One of two or more atoms having the same atomic number but different mass numbers.
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.
What are 2 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 in your own words?
isotope Add to list Share. 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.
How do you explain isotopes to children?
Isotopes are atoms that have the same number of protons and electrons, but a different number of neutrons . Changing the number of neutrons in an atom does not change the element. Atoms of elements with different numbers of neutrons are called “isotopes” of that element.
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.
How do you figure out isotopes?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu , you can calculate the mass of the atom.
What are the 3 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 .
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 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 Isodiapher example?
A set of nuclides which has a different number of protons and neutrons but there exists the same difference between the protons and neutrons are isodiaphers. For example, Thorium -234 and Uranium -238 are considered as isodiaphers. Hence, Thorium -234 and Uranium -238 are considered as isodiaphers.”
Can isotopes be created?
This can be done by firing high-speed particles into the nucleus of an atom. When struck, the nucleus may absorb the particle or become unstable and emit a particle. In either case, the number of particles in the nucleus would be altered , creating an isotope. One source of high-speed particles could be a cyclotron.
