WebThe lattice constants for gold and silver are almost identical (at 4.078 and 4.086 respectively). Intuitively, one might have expected that the gold atoms, being almost twice as heavy as silver atoms, would result in gold having a larger lattice constant but this is not the case. This is why the density of gold is almost twice that of silver. Web7 jun. 2024 · where r o is expressed in Å.
