10 x -10 = 1 Ångström

10 x -10 = 1 Ångström Atomic Sizes are on the order of 1 Angstrom = 10 x -10. http://hyperphysics.phy-astr.gsu.edu/hbase/nuclear/nucuni.html Molecular The smallest neutral molecule is the diatomic hydrogen (H2), with an overall length of roughly twice the 74 picometres (0.74 Å) bond length. Molecules commonly used as building blocks for organic synthesis have a dimension of a few Å to several dozen Å. http://en.wikipedia.org/wiki/Molecule
