Define an isotope. (a) What is the scientific definition of an isotope? (b) What is it used for? Describe with your own terms what an isotope is. Give the definition of an isotope and provide two examples. What is the definition of an isotope of an element and how is it different f...
Rhenium ({eq}^{75}Re {/eq}) has two naturally occurring isotopes with atomic weights 184.9530 and 186.9560. What is the percent abundance of the lighter isotope? Average Atomic Mass of an Element and Natural Abundance of Its Isot...
Percent abundance describes the prevalence of each of an element’s isotopes in nature.The percent abundance of each isotope is used in the calculation of an element’s average atomic mass. Many elements exist as two or more isotopes, which are versions of the same element that possess the sa...
- The term "average" in atomic mass signifies that it is not just the simple average of the isotopes' masses, but a weighted average. This means that the contribution of each isotope to the overall atomic mass is proportional to its abundance in nature. 4. Example of Chlorine Isotopes: ...
abundanceon Earth. Sometimes the value changes as scientists obtain more data about the isotope ratio of samples. The natural abundance of elements on the periodic table is not the same everywhere in the universe. The ratio of isotopes in the Sun or on Mars, for example, might be different....
Distinguish between the atomic number and the mass number of an element. What is an isotope?Element:An element consists of a single kind of atom and cannot break into different types of components. Element is formed of atoms and contains several subparts, including...

Deuterium is a stable isotope of hydrogen. In other words, deuterium isnotradioactive. Thenatural abundanceof deuterium in the ocean is approximately 156.25 ppm, which is one atom in 6,400 of hydrogen. In other words, 99.98% of hydrogen in the ocean is protium and only 0.0156% is deuterium...
The number of proton is the same as we are speaking of a particular atom, The relative abundance of the isotopes will define the final mass used with dealing with an element. Answer and Explanation:1 When dealing with isotopes, the relative abundanc...
