The isotopic mass is referred as mass of the most abundant isotope of an element. The relative isotopic mass of an isotope mass of one atom of the isotope = 12 x mass of one atom of 12C
How to find fractional abundance of an isotope How to find the natural abundance of an isotope How to find the relative abundance of isotopes How do you find the mass number of an isotope? How can one find the percent abundance of an atom when 3 isotopes and the average atomic mass are...

Their paper, accepted for publication in the journal Astrobiology, modeled habitability in the Milky Way based on three factors: supernova rates, metallicity (the abundance of heavy elements, used as a proxy for planet formation) and the time taken for complex life to evolve. They found that ...
Geological Survey, the abundance of gallium in Earth's crust is a measly 19 parts per million (silicon, by comparison, is 282,000 parts per million). The first person to isolate and recognize gallium as a new element was the French chemist Paul-Emile Lecoq de Boisbaudran in 1875. He ...
All of the elements that we know to exist are listed on the periodic table. If you notice, the atomic masses of each element are different, and they are generally decimal values. This value is the weighted average of each isotope for that element....
Chlorine-37 has an atomic mass of 36.966 amu and a percent abundance of 24.23%. To calculate the average atomic mass of chlorine, use the information in a periodic table of the element (see Resources) to find the (weighted) average but changing the percents to decimals: ...
units (amu). Even though each atom has roughly a whole number of atomic mass units, you will notice that the atomic mass on the periodic table is a decimal; that's because the number is a weighted average of the various naturally-occurring isotopes of an element based on their abundance....
external fields, carrier density, and impurities. We find that the Fröhlich interaction that dominates carrier relaxation contributes negligibly to spin relaxation, consistent with the spin-conserving nature of this interaction. Our theoretical approach may lead to new strategies to optimize spin and...
What determines whether an isotope is radioactive or not? What is an Atomic Mass Unit (AMU)? How do you show the number of protons and neutrons on a Bohr-Rutherford diagram? How does an atom try to fill its valence shell? How do you find the valency of an element? Ho...
