(e). See the answer. This problem has been solved! Aluminum is a soft, silvery-white, ductile metal in the boron group. De Morvea… In the 1750s German chemist Andreas Marggraf found he could use an alkali solution to precipitate a new substance from alum. People have used alum since ancient times for dyeing, tanning and to stop bleeding. One use of this salt is in the dyeing of cotton fabrics. Nov 8, 2012 - Explore Sam Corley's board "Aluminum Project" on Pinterest. b) 2Al(s) + 3Pb+ (aq) → 2Al3+ (aq) + 3Pb(s), 6.1 Al(OH)3 (s) +OH-(aq) → [Al(OH)4]-(aq), 6.2 Al(OH)3(s) + 3H+(aq) → Al(H2O)3]3+(aq). The electron configuration for Aluminum is 1s 2 2s 2 2p 6 3s 2 3p 1. Legal. Therefore number of electrons = 13. What is the electron configuration of Aluminum? The substance Marggraf obtained from alum was named alumina by French chemist Louis de Morveau in 1760. Periodic Table of the Elements Electron configuration of Gallium. The large initial outlay of energy is one important reason why recycling aluminum is such a good and cost-effective idea. Most of the aluminum today is produced by the Hall process which uses significant amounts of energy in the form of electricity to electrolyze aluminum metal from a molten salt mixture. Aluminum Electron Configuration . Electron configuration The arrangements of electrons above the last (closed shell) noble gas. December 1, 2008.
