Just a comment on “SI is lighter than AG on the atomic chart”.
While elemental silver is much more dense than elemental silicon
(10.49 g-cm-3 vs 2.33 g-cm-3), unfortunately the density of elements
doesn’t tend to always follow location on the periodic table. More
importantly, in this case, the density of elements often has little
or no bearing on the densities of compounds or alloys made from those
It would be extremely convenient if this were the case, but it is
