Know everything about Aluminium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure.
History of Aluminium
The element Aluminium was discovered by None in year 1825 in Denmark . Aluminium derived its name from alumina, a compound (originally aluminum)
Aluminium (or aluminum; see different endings) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth’s crust.
How to Locate Aluminium on Periodic Table
Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 13 to find Aluminium on periodic table.
Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Aluminium on periodic table look for cross section of group 13 and period 3 in the modern periodic table
Aluminium Atomic Structure and Orbital Properties
Aluminium atoms have 13 electrons and the electronic shell structure is [2, 8, 3] with Atomic Term Symbol (Quantum Numbers) 2P1/2.
Atomic Structure of Aluminium
Ground State Electronic Configuration of Aluminium - neutral Aluminium atom
The ground state electronic configuration of Neutral Aluminium atom is [Ne] 3s2 3p1. The portion of Aluminium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Ne]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.This is important as it is the Valence electrons 3s2 3p1, electrons in the outermost shell that determine the chemical properties of the element.
