Diameter of Gold atom in Angstroms from # of atoms in cube ...

Jun 27, 2009 · I am now supposed to find the diameter in angstroms of an atom of gold. I get that I need to find the number of atoms of gold in 1 cm, therefore, it should be the cube root of 5.9 x10^22, which I have as roughly 3.89 x 10^7 atoms/cm. From here, I divided 1 by the above result to get the diameter, and got 2.6 Angstroms diameter.

Atomic Structure. An atom is a complex arrangement of negatively charged electrons arranged in defined shells about a positively charged nucleus. This nucleus contains most of the atom's mass and is composed of protons and neutrons (except for common hydrogen which has only one proton). All atoms are roughly the same size. A convenient unit of length for measuring atomic sizes is the angstrom ...
