<p>[QUOTE=&quot;desertgem, post: 2714124, member: 15199&quot;]These are metallic bonds, not covalent nor ionic, all of the electrons are in clouds , so there would be no elongations of bonded structures that would visible except on the level of the microscopes that can image actual atoms, and that is extremely difficult with metals. You can hammer, compress, etc. gold to a sheet thin enough for light to see through, but there will be no grains, elongated or not. Copper has less ductility and copper mix even less, but<span style="color: #ff0000"> ONLY <span style="color: #000000">non metallic should form grains, not the coin metals (IMO). I will have to dig out&nbsp; Metallic bond resources when College reopens from SB. </span></span>[/QUOTE]</p><p><br /></p>
