:any of the forms of an element that differ in the number of neutrons in an atom isotopic ˌī-sə-ˈtäp-ik -ˈtō-pik adjective isotopically -ˈtäp-i-k(ə-)lē -ˈtō-pi- adverb Medical Definition isotope noun
- Atomic Number (Z): This is the number of protons in the nucleus of an atom. For isotopes of the same element, this number remains constant. - Mass Number (A): This is the total number of protons and neutrons in the nucleus. Since isotopes differ in the number of neutrons, their ...
Because each element is distinctive of its atomic number, all atoms of a particular element must have the same number of proton. The atomic number of carbon is 6. Then all kinds of carbon atoms must have 6 protons in their nuclei. So these atoms...
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos (ἴσος"equal") and topos (τόπος"place"), meani...
Most elements exist in two or more forms, known as isotopes. Isotopes have the same number of protons but differ in their number of neutrons, resulting in different masses. The lighter form is generally the more common one (Hobson & Wassenaar 2008). This variation in the relative abundance ...
Book series1984, Advances in Radiation Biology Howard M. Prichard, Thomas F. Gesell Explore book VIII Summary The isotopes of radon and their short-lived daughters are important constituents of the natural radiation environment. Radon daughters have been clearly associated with the induction of lung ...
isotopes have the same chemical properties as their elements but different chemical properties. This is because isotopes of an element have the same number of electrons as an atom of that particular element. The electron arrangement is what affects chemical properties, and isotopes have the same ele...
, 1971), it was not until isotopic studies of hydrothermally altered basalts from ophiolite suites that the eclogite signatures were interpreted as an indication of a crustal prehistory for these rocks (Jagoutz et al., 1984). Such data, along with their omphacitic pyroxenes, are some of the...
On the other hand, physical properties, such as the boiling point and melting point of an element, depend on its atomic mass number. A difference in the mass number lends different physical properties to an isotope from its parent. However, the nuclear properties of isotopes differ from one ...
Isotopes are variations of elements with the same number of protons but different numbers of neutrons, affecting mass. Isomers have identical molecular formulas but differ in atom arrangements or bonds, influencing structure and properties.
