单词	isotone
释义	isotone i·so·tone I0256600 (ī′sə-tōn′)n. One of two or more atoms whose nuclei have the same number of neutrons but different numbers of protons. [Alteration of isotope (with n for neutron replacing p as though for proton).] isotone (ˈaɪsəˌtəʊn) n (Chemistry) one of two or more atoms of different atomic number that contain the same number of neutrons i•so•tone (ˈaɪ səˌtoʊn) n. one of two or more atoms having an equal number of neutrons but different atomic numbers. [< French (1934), alter. of isotope, by substituting n (the initial letter of neutron) for p (the initial letter of proton)] isotone Isotone One of two or more atoms which display a constant difference A - Z between their mass number A and their atomic number Z. Thus, despite differences in the total number of nuclear constituents, the numbers of neutrons in the nuclei of isotones are the same. The numbers of naturally occurring isotones provide useful evidence concerning the stability of particular neutron configurations. For example, the relatively large number (six and seven, respectively) of naturally occurring 50- and 82-neutron isotones suggests that these nuclear configurations are especially stable. On the other hand, from the fact that most atoms with odd numbers of neutrons are anisotonic, one may conclude that odd-neutron configurations are relatively unstable. See Nuclear structure isotone [′ī·sə‚tōn] (nuclear physics) One of several nuclides having the same number of neutrons in their nuclei but differing in the number of protons. isotone isotone [i´so-tōn] one of several nuclides having the same number of neutrons, but differing in number of protons in their nuclei. i·so·tone (ī'sō-tōn), One of several nuclides having the same number of neutrons in their nuclei, for example, ³⁹₁₉K and ⁴⁰₂₀Ca with 20 each, ⁵⁶₂₆Fe and ⁵⁸₂₈Ni with 30 each. [iso- + G. tonos, stretching, tension] i·so·tone (ī'sō-tōn) One of several nuclides having the same number of neutrons in their nuclei. [iso- + G. tonos, stretching, tension] i·so·tone (ī'sō-tōn) One of several nuclides having the same number of neutrons in their nuclei. [iso- + G. tonos, stretching, tension]
