Etiquette in retail is sometimes summarized as The customer is always right.. There are always two sides to the case, of course, and it is a credit to good manners that there is scarcely ever any friction in stores and shops of the first class.
Part of the Computing fundamentals glossary: An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element. The nuclei of most atom s contain neutrons as well as protons.
Best Answer: Define isotope: same place meaning same spot on the periodic table, therefore all of the chemical properties are the same. Different number of neutrons in the nucleus, so it has a different atomic weight.Different isotopes can be more or less radioactive, have different 1/2 lives or be fissile.Source(s): http://en.wikipedia.org/wiki/Isotopes http://ie.lbl.gov/education/isotopes.htm.imilarities: same number of protons, same number of electrons, same atomic number Differences: different number of neutrons, different mass.
