", ground state electronic configuration of neutral tantalum is. Tantalum is a greyish silver, heavy, and very hard metal. Copyright 1995 - 2020 Kenneth L Barbalace (. In this process tantalum salts are extracted into the ketone MIBK (methyl isobutyl ketone, 4-methyl pentan-2-one). You can reference the WebElements periodic table as follows:"WebElements, https://www.webelements.com, accessed November 2020. When pure, it is ductile and can be drawn into fine wire, which can be used as a filament for evaporating metals such as aluminium. Electrolysis of molten fluorides is also used. The ground state electronic configuration of neutral tantalum is [Xe].4f14.5d3.6s2 and the term symbol of tantalum is 4F3/2. 1995 - 2020. Reactions of tantalum as the element with air, water, halogens, acids, and bases where known. Members of a group typically have similar properties and electron configurations in their outer shell.
