Unreactive metals
WebPlatinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. WebExtraction of metals Ores.

WebJul 19, 2015 · One of the reasons why non reactive metals are good conductors is that they are good at staying as metals. Most metals react with the atmosphere to form oxides. … WebThe elements are generally classified as metals, metalloids, nonmetals (including the halogens), and the noble gases. The metals found in the middle of the table, from columns 3 - 12 are called the transition metals and occupy the d orbitals. The metals found in the two rows at the bottom of the table are called the Lanthanide series and the ...
WebWhy are the noble metals inert? I am wondering: The noble 'gases' are inert because they have closed shells and don't want to give that up. But the noble metals, such as Copper, Silver, Rhodium, Gold, don't seem to have this. For example, Rhodium has electron configuration 4 d 8 5 s 1. To me, this looks very similar to the alkali metals, which ... WebThis is because more reactive metals have a greater tendency to form its positive ions. E.g. Mg can displace ZnSO 4 but Cu, Pb and Fe cannot. · The more reactive a metal is, the …
