Lithium mass amu

Web8 okt. 2024 · Since neutrons are neither attracted to nor repelled from objects, they don't really interact with protons or electrons (beyond being bound into the nucleus with the protons). The third column shows the masses of the three subatomic particles in "atomic mass units." An atomic mass unit ( amu) is defined as one-twelfth of the mass of a … WebLithium has two isotopes, 6 Li and 7 Li, with masses of 6 amu and 7 amu respectively. If Lithium has an atomic weight of 6.94 amu, we can determine the abundance of each isotope. First, we define one. of the abundances as x. In this case, the abundance of 6 Li will be x. This means that the abundance of 7 Li= 1-x.
