Neodymium (Nd) Standard atomic mass: 144. ... Isotopes are any of the several different forms of an element each having different atomic mass (mass number). ... The periodic table of the chemical elements A chemical element, or element for short, is a type of atom that is defined by its atomic number; that is, by the number of protons in its nucleus. ... It has been suggested that List of elements by atomic number be merged into this article or section. ... This article or section does not adequately cite its references or sources. ...

Half lives are indicated by the color of each isotope's cell (see color chart to the right). Colored borders indicate half lives of the most stable nuclear isomer states. Half-Life For a quantity subject to exponential decay, the half-life is the time required for the quantity to fall to half of its initial value. ... 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. ...

The whole table can be found in one piece at Isotope table (complete). This isotope table shows all of the known isotopes of the chemical elements, arranged with increasing atomic numbers (proton numbers) from left to right and increasing neutron numbers from top to bottom. ...

Isotope (886 words)
	Isotopes of a chemical element are atoms whose nuclei have the same atomic number, Z, but different atomic weights, A.
	In scientific nomenclature[?], isotopes are specified by the name of the particular element followed by a hyphen and the number of nucleons (protons and neutrons) in the atomic nucleus (e.g., iron-57, uranium-238, helium-3).
	The atomic mass for an element in the periodic table is the average of the natural abundance of the isotopes of that element.

isotope Information Center - isotope (1087 words)
	Isotopes are forms of an element whose nuclei have the same atomic number–-the number of protons in the isotopes of carbon nucleus--but different atomic masses because they contain different numbers of neutrons.
	In scientific nomenclature, isotopes (nuclides) what practical applications do isotopes have are specified by the name of the particular element by a hyphen and the number of nucleons (protons and neutrons) in the atomic nucleus (e.g., helium-3, carbon-12, carbon-14, stable isotopes iron-57, radioactive isotope uranium-238).
	The vibrational modes radioactive isotopes in medicine of a molecule are determined by its shape and by the masses of its constituent model of isotope neon 21 atoms.
