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.
What is isotope and example?
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 . ... For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.
What is isotopes very short answer?
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. Atomic mass adds to that the number of neutrons in the nucleus.
What is the correct definition of isotope mass?
Isotopic mass refers to the average mass of all the isotopes of a specific element . An element can contain a defined number of protons in their nucleus, but the number of neutrons can vary. ... The isotopic mass is calculated by summing the result between the abundance and the atomic mass of each isotope of an element.
What is an isotope definition for dummies?
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 . Every chemical element has one or more isotopes. The isotopes of an element occupy the same position in the periodic table.
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).
What are 3 examples of isotopes?
Isotope Examples
The isotopes of hydrogen are hydrogen-1 (protium, which is a stable isotope), hydrogen-2 (deuterium, which is another stable isotope), and hydrogen-3 (tritium, which is a radioisotope). Uranium-235 and uranium-238 are two isotopes of uranium.
How do you list isotopes?
An isotope and/or nuclide is specified by the name of the particular element (this indicates the atomic number) followed by a hyphen and the mass number (e.g. helium-3, helium-4, carbon-12, carbon-14, uranium-235 and uranium-239).
What is called Isobar?
Definition of Isobar
Isobars are defined as. The atoms that have same number of nucleons . Isobars of different chemical elements have different atomic number but have the same mass number. Alfred Walter Stewart in 1918 suggested the term isobars.
Which of the following best describes isotope?
Which of the following best describes an isotope? Structurally variant atoms , which have the same number of protons (and electrons), but differ in the number of neutrons they contain.
Which of the following is a correct definition of an isotope?
According to the nuclear science, the correct definition of isotope is the atom of an element having the same atomic number but different mass number are called isotopes. The isotopes of an element differ in the number of neutrons in their nuclei.
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.
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 are isotopes 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.
