The meaning of ISOTOPE is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. How to use isotope in
atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8...

More Commonly Known as Relative Atomic Mass Atomic massis used interchangeably with atomic weight, although the two terms don't mean precisely the same thing. Another issue is that "weight" implies a force exerted in a gravitational field, which would be measured in units of force, like newtons...
(Chemistry) the sum of all the relative atomic masses of the atoms in a molecule; the ratio of the average mass per molecule of a specified isotopic composition of a substance to one-twelfth the mass of an atom of carbon-12. Symbol:MrAbbreviation:r.m.m.Former name:molecular weight ...
Relative Formula Mass Definition A related term you should know is relative formula mass (relative formula weight). This simply means the calculation is performed using relative atomic weight values for the elements, which are based on the natural isotopic ratio of elements found in Earth's atmosph...
Therefore, only the correct formula for sulfadimethoxine is found at the 2-ppm mass error limit. For more information on the use of the relative isotopic mass defect to limit molecular formulas, see reference number 3 from our book on LC/TOF- MS analysis. Generally, the error limits on ...
There are two reasons for the difference between mass number and isotopic mass, known as themass defect: Theneutron isslightlyheavierthan theproton, increasing the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on12C with equal numbers o...
Information from his and other laboratories accumulated rapidly in the ensuing years, and by 1935 the principal isotopes and their relative proportions were known for all but a handful of elements. Nuclear stability Isotopes are said to be stable if, when left alone, they show no perceptible ...
The meaning of ISOTOPE EFFECT is the variation of certain characteristics (as density and spectrum) of an element in accordance with the mass of the isotopes involved.
