Electron configuration
[Kr] 4d10 5s1
A neutral Silver atom has 47 electrons (equal to its proton count). Choosing a different isotope above changes only the neutron count.
Shell distribution
Shell 12 e⁻Shell 28 e⁻Shell 318 e⁻Shell 418 e⁻Shell 51 e⁻
Electrons fill inner shells before outer ones; the outermost (valence) shell drives the element's chemistry.

Cosmic origin
Where Silver comes from
Neutron star mergers
Mostly an r-process element: silver is a product of rapid neutron capture.
Simplified origin map — many elements form through more than one astrophysical pathway.
