  Encyclopedia: Isotope table (divided)   (Site not responding. Last check: 2007-11-03)
Isotopes are forms of a chemical element whose nuclei have the same atomic number, Z, but different atomic masses, A. The word isotope, meaning at the same place, comes from the fact that all isotopes of an element are located at the same place on the periodic table.
In scientific nomenclature, isotopes 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, iron-57, uranium-238).
The atomic mass for an element in the periodic table is the average of the natural abundance of the isotopes of that element.

Isotopes are forms of an element whose nuclei have the same atomic number–-the number of protons in the nucleus--but different atomic masses because they contain different numbers of neutrons.
The word isotope, meaning at the same place, comes from the fact that all isotopes of an element are located at the same place on the periodic table.
In scientific nomenclature, isotopes (nuclides) 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, iron-57, uranium-238).

 World War 1 and 2 - Stable isotope   (Site not responding. Last check: 2007-11-03)
Those isotopes that are not radioactive are called stable.
While stable isotopes of the same element maintain the same chemical characteristics and therefore react in the same way, the mass difference as a result of an extra few neutrons results in partial separation of the light from heavy isotopes during chemical reactions (isotopic fractionation).
For example, the difference in mass between the two main isotopes of hydrogen H-1 (1 proton, no neutron) and H-2 (also known as deuterium; 1 proton, 1 neutron) is almost 100%.

A hard line of listed isotopes are those with half-lives of 24 hours or greater.
This is done because the average person would have no chance of comming into contact with any other isotopes.
A softening of the line exists in the listing of isotopes with shorter half-lives that are likely to come into contact with "normal persons".

Stable isotopes of the same element have the same chemical characteristics and therefore behave almost identically.

 PERIODIC SYSTEM OF ELEMENTS   (Site not responding. Last check: 2007-11-03)
The periodic table of the chemical elements is a display of known chemical elements, arranged by electron structure so that many chemical properties vary regularly across the table.
The original table was created without a knowledge of the inner structure of atoms: if one orders the elements by atomic mass, and then plots certain other properties against atomic mass, one sees an undulation or periodicity to these properties as a function of atomic mass.
Despite their dramatic differences in mass within the group, their allotropes have very similar properties: They are all highly corrosive (meaning they combine readily with metals to form metal halide salts); chlorine and fluorine are gases, while bromine is a very low-boiling liquid; chlorine and bromine at least are highly colored.
