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). WebWhat is the approximate interatomic spacing between atoms? 0.3 nm. ... higher binding energy and higher melting point, greater force to stretch the bond, so greater modulus of elasticity.
