Atomic Mass vs. Mass Number: Unravel the Mystery By Todd Helmenstine Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes. The atomic weight can change because it depends on our understanding of how much of each isotope of an...
atomic number vs. mass number atomic mass vs. atomic number atomic number vs. atomic weight Discover More Example Sentences There are “light” and “heavy” rare earths, based on their atomic number, and global demand for these metals is climbing. ...
So deuterium has one neutron and since neutrons have mass, deuterium has more mass than protium. So isotopes have different masses because they differ in terms of number of neutrons. Notice though, that they have the same atomic number, they have the same number of protons in the nucleus...
• Atoms that have the same number of protons, but different number of neutrons • They are the same element with a different mass –Same atomic number –Different mass numbers Mass Number vs. Atomic Mass • The mass number tells the number of protons and the number of neu...

today actually refer to unified atomic mass units or u. For standardization a specific atomic nucleus (carbon-12 vs. oxygen-16) had to be chosen because average mass of a nucleon depends on the count of the nucleons in the atomic nucleus due to mass defect. This is also why the mass ...
