Silver nugget Silver nugget other side
Silver is the most abundant noble metal and is widely used for jewellery, coins and for technical applications. It has the highest electric and thermic conductivity and the whitest color of all metals. Silver compounds, like silver bromide, are used for photographic films, as some of them are very photosensitive. It occurs in its pure form in nature, but rarely as nugget, like this one shown here.
