Chemical and Physical Properties of Isotopes We have seen that isotopes differ in mass number. The mass number has very little bearing on chemical reactions; therefore thereactivityand chemical reactions of an element's different isotopes are almost identical. The physical properties of atoms, however...
One of two or more atoms having the same atomic number but different mass numbers. [iso-+ Greektopos,place (so called because the isotopes of a chemical element occupy the same position in the periodic table of elements).] i′so·top′ic(-tŏp′ĭk)adj. ...
The number of neutrons contained in the nucleus of most elements is variable. Nuclei with the same number of protons and different numbers of neutrons are calledisotopes. The number of protons a nucleus has is given by the element's atomic number, while the number of protons plus neutrons is...
When you remove or add a neutron to the nucleus of an atom, you don’t technically get a new element, but you do have a new type of the same element in your hand. This new type is called an “isotope” of the element. Isotopes are formally defined as elements with the same number...
isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes. An atom is first ...
Chemistry. any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the 81 stable elements, in addition to ...
The meaning of RADIOCHEMISTRY is a branch of chemistry dealing with radioactive substances and phenomena including tracer studies.

1.(Physiology)physiol(of two or more muscles) having equal tension 2.(of a drink) designed to replace the fluid and salts lost from the body during strenuous exercise 3.(Chemistry) Also:isosmotic(of two solutions) having the same osmotic pressure, commonly having physiological osmotic pressure...
there is virtually complete equilibrium in the molecular energy levels belonging to the two conformers. Except where the context requires otherwise, a group of molecules containing different isotopes in their natural abundances will be regarded as all being the same species. Groups of atoms are ...
