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.The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.The equation is the one which describes radioactive decay: If one of these assumptions has been violated, the simple computation above yields an incorrect age.The isotope of an element is defined by the nucleon number, which is the sum of the number of protons and the number of neutrons in the atomic nucleus.The nucleon number is customarily written as a superscript preceding the chemical symbol for the element.

Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.Isotopes are distinguished from each other by giving the combined number of protons and neutrons in the nucleus.For example, uranium 235 is the isotope of uranium that has 235 protons and neutrons in its nucleus rather than the more commonly occurring 238. noun A nearly identical person; near double: Like his isotope Paglia, Rush Limbaugh can be counted on to bury the occasional nugget of truth beneath his avalanche of infuriating extrapolation and phony statistics/It actually IS you.
