Silver Element Facts - Periodic Table of Elements and ...

Silver and lead often appear together in nature, for example in the mineral galena which is mainly lead sulfide. Galena actually looks metallic (see image) and would have caught the eyes of people looking for metals. The silver objects found in Greece, Turkey and Kish were made of silver that was refined from lead-containing ores such as galena.


The zinc atom has a radius of 134 pm and a Van der Waals radius of 210 pm. Zinc was discovered by Indian metallurgists prior to 1000 BC and first recognized as a unique element by Rasaratna Samuccaya in 800. Zinc was first isolated by Andreas Marggraf in 1746.

The Properties and Uses of Zinc Metal

Jun 25, 2019· Man-made zinc alloy products have been reliably dated as far back as 500 BC, and zinc was first intentionally added to copper to form brass around 200-300 BC. Brass supplemented bronze during the Roman Empire in the manufacture of coins, weapons, and art, and remained the chief use of zinc until 1746 when Andreas Sigismund Marggraf knowingly isolated the pure element.

Uses of Lead | Lead Deposits and Resources

Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).
