+		<name>Nuclear Isomer</name>
+		<desc>A nuclear isomer is a metastable or isomeric state of an atom caused by the excitation of a proton or neutron in its nucleus so that it requires a change in spin before it can release its extra energy. They decay to lower energy states of the nuclide through two isomeric transitions:[br] -> &#947;- emission (emission of a high-energy photon)[br] -> internal conversion (the energy is used to ionize the atom)[br] Contrast this with the definition of a chemical isomer, the more common use of the word. Also contrast with the meaning of isotope, in which the difference is the number of neutrons in the nucleus. Metastable isomers of a particular atom are usually designated with an "m" (or, in the case of atoms with more than one isomer, 2m, 3m, and so on). This designation is usually placed after the atomic symbol and number of the atom (e.g., Co-58m), but is sometimes placed as a superscript before (e.g., [sup]m[/sup]Co-58 or [sup]58m[/sup]Co).</desc>

+		<desc>The Ionic Radius is the radius of a charged atom, a so called ion. The ion can have a positive or a negative charge. The charge of the ion which radius you see is also displayed in Kalzium. A positive ion has less electrons in its shell then the atom, a negative ion has more electrons. Therefore, a postive ion has a smaller radius than its atom and vice versa.</desc>
