Copper is the least reactive of these five … WebJan 17, 2024 · To understand why noble metals are some of the least reactive metals, it is important to know their electronic configuration. The chemical reactivity of elements is affected by the arrangement of electrons around the nucleus, which allows the atom to remain stable. Stability is attained when the element has completely filled electron shells.
WebSuch elements are also identified as reducing agents, as they reduce the other species/element present in the reaction mixture. As is evident from the above reactivity series, among iron (Fe), copper (Cu), aluminium (Al), and calcium (Ca), Copper is placed at the lowest position i.e., it is the least reactive metal.
