These electrons determine the chemistry of the atom.
These particles may be accompanied by the emission of energy in the form of electromagnetic radiation known as gamma rays. Radioactive products which are used in medicine are referred to as radiopharmaceuticals.
This is a branch of medicine that uses radiation to provide information about the functioning of a person's specific organs or to treat disease.
Isotopes | Stable & Unstable | Applications | Definitions | Diagnosis | Radiotherapy | Biochemical Analysis Diagnostic/Therapeutic Radiopharmaceuticals | Discovery | Isotopes in Medicine | Terms & Concepts An isotope is one of two or more species of atoms of a chemical element with the same atomic number (same number or protons in the nucleus) and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. An atom is first identified and labeled according to the number of protons in its nucleus.
This atomic number is ordinarily given the symbol Z.
An "isotopically labeled compound" has one or more of its atoms enriched in an isotope.
