![]() What is the difference between Au and Ag? 100% of gold found naturally is isotope Au-197. It’s abundance in the earth’s crust is 0.004 ppm. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek. For example, the Latin word for Gold is aurum so the Periodic Table symbol Au comes from the first two letters of its Latin name. Toxic: Over accumulation of silver in water bodies is harmful and toxic to aquatic animals.Most of the elements’ abbreviations are derived from Greek and Latin, or other ancient origins.In large quantities they damage organs and even causes narcosis. Ingestion: In small quantities it causes minor discomfort to organs.Relatively large amount can even cause eye injury. Irritation: Exposure to small amounts of silver causes eye and skin irritation.Silver nanoparticles have much lower melting points than relatively larger particles of silver. Nanoparticles: Silver nanoparticles have been used as antibacterials and antifungals also they have been used in conductive inks.Powdered silver is use in paste preparations for conductor layers, electrodes, ceramic capacitors, etc. Electronics: Silver is used for making high quality connectors for RF, VHF, cavity filters etc.Medicine: Silver is used in wound dressing due to its antibacterial properties.Usually silver plating is applied instead of making the items out of pure silver. Silverwares: Silver has antibacterial properties thus it is suitable for making cutlery.Equipments: Equipments required for chemical activity have silver in it because silver has low reactivity.For most of the chemical engineering applications coarser-grained form of silver is used so that it doesn’t over oxidise the ongoing process. Finely divided silver catalysts are capable for causing complete oxidation of organic substances to carbon dioxide and water. ![]()
