The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137...
An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...
The AMU difference occurs because U-238, which is the most abundant naturally occurring uranium isotope, has three more neutrons in its atom than U-235. U-235 is used in nuclear reactors to generate nuclear energy by the process ofnuclear fission. It is also one of the key ingredients of...
It is defined as one-twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and has a value of1.66054×10−27kg. Masses of protons, neutrons, and electrons in various units. References: ...
