How big is an atom? - University of Pittsburgh

WebThe size of atoms can be estimated with the use of Avogadro's number along with the atomic mass and bulk density of a solid material. From these, the volume per atom can be determined. The cube root of the volume is an estimate of the diameter of the atom. For carbon, the molar mass is exactly 12, and the density is about 2 gm/cm 3. WebThis means that the size of the nucleus is smaller than 4×10 -14 m. The sizes of the nuclei of various elements have been accurately measured after conducting many more iterations of the experiment. Having done this, a formula to measure the size of the nucleus was determined. R = R 0 A 1 3.
