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
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...

John Daltonfirst suggested a means of expressing relative atomic mass in 1803. He proposed the use of hydrogen-1 (protium). Wilhelm Ostwald suggested that relative atomic mass would be better if expressed in terms of 1/16th the mass of oxygen. When the existence of isotopes was discovered in...
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 ...
Homework Statement 1) "The relative atomic mass of antimony is 121.8. Antimony exists as two isotopes; antimony-121 and antimony-123. Calculate the relative abundances of the two isotopes." 2) "The relative atomic mass of rubidium is 85.5. Rubidium consists of two isotopes, rubidium-85 and....
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...
It is commonly said that the phase of coherent states can't be measured, just the relative phase between two coherent states. A qubit example: define the states $$|\phi\rangle=[|0\rangle+\exp (\mathrm{i} \phi)|1\rangle] / \sqrt{2}$$ and the measurement operators... ...
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 ...
astronomical objects, voted to revoke Pluto’s planetary status and place it under a new classification calleddwarf planet. For a discussion of that action and of the definition ofplanetapproved by the IAU,seeplanet. Understand the relative size of the Sun, the Moon, and other solar system ...
