Isotope definition

Aug There are 2isotopes of the stable elements available to study. This is the definition of an isotope along with examples. All isotopes of a given element have the same number of protons in each atom. Isotopes are variants of a particular chemical element which differ in neutron number.

An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutrons, in addition to the number of protons that uniquely defines the element. 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 to Carbon 13. Elements are defined by the number of protons in the atomic nucleus. For example, an atom with protons must be carbon, and an atom with protons must be uranium. In addition to protons, the atoms of nearly every element also contain neutrons.

The mass of a neutron is almost identical to that of a . A secondary school revision resource for AQA GCSE Additional Science about radiation, atoms and isotopes. Not all atoms of an element are identical – atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes.

In this lesson, we will discuss the examples and types of isotopes.

That type of atom is called an isotope. Definition of isotope – each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuc. Dec The three share the place in the periodic table assigned to atomic number and hence are called isotopes (from the Greek isos, meaning “same,” and topos, signifying “place”) of hydrogen. Many important properties of an isotope depend on its mass.

The total number of neutrons and protons (symbol A), . When discussing the meaning and properties of isotopes in general, as on this page, the same element part may often be assumed. Chemical Properties: The chemical properties of most isotopes are the same or very similar. This is because chemical reactions generally involve electrons rather than protons or neutrons.
