Binding energy and interatomic spacing
Webreal one, and the repulsion force is less. It means that the binding energy of such ion is bigger and dE/dR for it is bigger than that for the real ion. Let us build the following H2+ ion model: near the bottom of the potential well energy is described by (4), at bigger distances it is described by the same equation but K and λ depends on R.

Binding energy and interatomic spacing
Did you know?
WebThe cohesive energy of NaCl can be described by the function, U tot = N (zλe−R/ρ− αe2 4πϵ0R). U t o t = N ( z λ e − R / ρ − α e 2 4 π ϵ 0 R). Here N N is the number of primitive unit cells in the crystal, R R is the … 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).
