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
Related to this QuestionWhat was the first ever discovered element? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? How do you tell how many valence electrons there are in an element b...
Atomic mass unit is one-twelfth the mass of an atom of carbon-12 (12C), the most common carbon isotope. Nonetheless, the termapproximatematters because the masses of individual atoms in elements -- other than carbon -- are not whole numbers (see above examples). This is because mass is ...
neutron, but it usually doesn't, so the mass number of hydrogen is 1. Oxygen, on the other hand, has an equal number of proteins and neutrons, which raises its mass number to 16. Subtracting an element's mass number from its atomic mass tells you the number of protons in its nucleus...
3\. Below the symbol is the atomic mass. While this number is a weighted average of the masses of all isotopes of the element, if you round the number to the nearest whole number you will find the mass number of the most common isotope. For carbon the mass number (M) is 12. This...

Can you tell me the formula for calculating the time it will take a pendulum to stop swinging? Explain how to find which method of depreciation is to be used based on the asset. If you know the atomic number and the mass number of an isotope of an element, how can you determine the...
table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in anatom's nucleus, which generally coincides with increasing atomic mass. ...
Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing....
To calculate the atomic mass of asingle atomof an element, add up the mass ofprotons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons. Th...
