Complete and detailed technical data about the element Aluminum in the Periodic Table. Atomic Number: 13: Atomic Weight:: Density: 2.7 g/cm 3. Aluminum (Al), also spelled aluminium, chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most abundant metallic element in Earth ’s crust and the most widely used nonferrous metal.

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.

Picture Of Aluminum Atomic Number

Aluminium is a monoisotopic element and its atomic weight is determined solely by its isotope 27Al. The Commission last revised the standard atomic weight of aluminium in 2017 based on the latest Atomic Mass Evaluation by IUPAP.

26Al is radioactive with a half-life of 0.705(24) Ma, too short for survival of a detectable amountof primordial isotope. However, 26Al is recognized as a spallation product of argon from cosmic rays. In addition,secondary cosmic rays including muons interact with Si-bearing rocks to produce 26Al in measurableamounts, but far below levels that would affect the atomic-weight value in normal materials.

27Al is the most abundant isotope in the earth's crustal rocks with an uneven atomic number.

Aluminum Have Atomic Number

Aluminium
Ar(Al) = 26.981 5384(3) since 2017
The name derives from the Latin, alum and alumen for 'stringent' because the early Romans called anysubstance with a stringent taste alum. The element was known in prehistoric times. In 1825, the Danishphysicist, Hans Christian Oersted, isolated impure aluminium. The pure metal was first isolated by theGerman chemist Friedrich Wöhler in 1827.
