Distances on the atomic scale are often expressed in units of angstroms (Å), with one angstrom being equal to 1 x 10-10 meters.  The element with the largest atomic diameter is cesium, experimentally measured as 5.20 Å.  How many cesium atoms can fit side-by-side on the head of a dime (a distance of 10.0 mm)? cesiumatom.png
