isotopes : Isotopes are forms of an element whose nuclei have the same atomic number–-the number of protons in the nucleus--but different mass numbers because they contain different numbers of neutrons..

  www.mindbites.com Professor Harman explains isotopes and atomic mass in this lesson covering atomic structure. Most elements exist in nature as more than one isotope. Isotopes are atoms that have the same number of protons as the element but a different number of neutrons. The number of protons always remains the same, as this number (also known as the atomic number) is what determines the element. Prof. Harman also introduces atomic mass units, or amu's, which are a more convenient unit for ...

  Rare isotopes rock. A return to the scene of my first encounter with accelerator physics -- the NSCL (National Superconducting Cyclotron Laboratory) has won a bid to upgrade their nucleus-accelerator to the FRIB (Facility for Rare Isotope Beams).

Question : How are the isotopes of an element alike and how are they different?

Answer : Isotopes are the same element with the same number of electrons in the outer shells and the same number of protons in the nucleus. But they differ in the number of neutrons in the nucleus...   More from Yahoo Answers

Question : That basicallly sums up the question. Why are some isotopes radioactive, what are the magic numbers, and why do these magic numbers make certain atoms, (or isotopes?) extremely stable?

Answer : Magic numbers are the nuclear equivalent to closed atomic shells which are responsible for the proprieties of the periodic table. They are very stable nuclei much helium, neon, krypton, etc. are very stable atoms. See the reference for more details...   More from Yahoo Answers
