WebIn chemical discussions, the unit of length—atomic sizes, bond lengths (interatomic distances)—has typically been Å (angstroms), where, again by definition, 1 Å equals 10 −8 cm or 10 −10 m because that is the typical interatomic spacing. More recently, length is often written in picometers (pm; 1 Å equals 100 pm). WebThus, after the binding energy has been removed, binding energy = mass change × c 2. This energy is a measure of the forces that hold the nucleons together. It represents energy that must be resupplied from the environment for the nucleus to …
