Isotopes. The term "isotopes" refers to atoms of an element that have the same quantity of protons but differ in the number of neutrons they possess. Examples of Radioisotopes in Biology. Learn vocabulary, terms, and more with flashcards, games, and other study tools. ADVERTISEMENTS: Isotopes are chemical elements that have the same atomic number (i.e., the number of protons in the nu­cleus of the atom) but different atomic masses (i.e., the sum of the number of protons and neutrons in the nucleus). What are the elements that go with the acronym chonps? 50 terms. Where are the electrons in an atom found? The table below sum-marizes some generally useful information about some common isotopes. Learn isotope with free interactive flashcards. Protons and neutrons have an assumed mass of 1, so the combined number of protons and neutrons in the nucleus equals the atom's mass number. A pure substance; cannot be separated by ordinary chemical means into simpler substances, Smallest unit of an element (basic building block) that still maintains the properties of that element; can have different number of neutrons.

A cation is a positive ion. S.S. Assonov, Pier A. de Groot, in Handbook of Stable Isotope Analytical Techniques, 2009. A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. Add them all up together. Find a woman in my area! Carbon-14 (14 C) is unstable and only occurs in trace amounts. atom: The smallest possible amount of matter which still retains its identity as a chemical element, consisting of a nucleus surrounded by electrons. LIT SAT2. This does not affect the atomic number of the atom, but it does affect the mass. sgnash2014. isotope [i´so-tōp] a chemical element having the same atomic number as another (i.e., the same number of nuclear protons), but having a different atomic mass (i.e., a different number of nuclear neutrons). One more neutron and one more proton than hydrogen-1. Unstable isotopes most commonly emit alpha particles (He 2+) and electrons. An ion is a negative ion. Radioactive Isotopes and Biology. 21 terms.
