2. Isotope
   [band] Isotope was a British jazz-rock band based around guitarist Gary Boyle. Boyle founded the band in June 1972 and a first album, Isotope, was largely composed by keyboardist Brian Miller. Jeff Clyne was on bass and Nigel Morris was on drums. However, Clyne and Miller left in 1974 to be ...

7. Isotope
   A variation of an element that has the same atomic number of protons but a different weight because of the number of neutrons. Various isotopes of the same element may have different radioactive behaviors, some are highly unstable..

8. Isotope
   One of two or more forms of an element that have the same number of protons (atomic number) but differing numbers of neutrons (mass numbers). Radioactive isotopes are commonly used to make DNA probes and metabolic tracers.

11. Isotope
    Isotopes are different atoms of the same element, therefore having the same number of protons, but containing a different number of neutrons. Their relative masses are different because it is essentially the protons and neutrons in the nucleus that make up the mass of the atom. Chlorine, for example...

12. Isotope
    An isotope represents Atoms of the same Element that have the same number of Protons but a different number of Neutrons . They therefore have different Atomic Masses but the same chemical properties. A radio-isotope is an isotope which is Radioactive .

15. Isotope
    An atomic form of an element having a particular number of neutrons. Different isotopes of an element have the same number of protons but different numbers of neutrons and hence different atomic mass, eg. U-235, U-238. Some isotopes are unstable and decay (qv) to form isotopes of other elements

16. Isotope
    One of perhaps several different species of a given chemical element with the same number of protons, which are distinguishable by variations in the number of neutrons in the atomic nucleus but indistinguishable by chemical means.

17. isotope
    isotopic; isotopy. Compare with isomer, allotrope, isobar, and isotone. Atoms or ions of an element with different numbers of neutronsin their atomic nucleus. Isotopes have the same atomic number but different mass number. Isotopes have very similar chemical properties but sometimes differ greatly in nuclear stability.
