An aluminium atom has 13 electrons, arranged in an electron configuration of 3s 2 3p 1, with three electrons beyond a stable noble gas configuration.

The electron configuration for Aluminum is 1s2 2p2 3s6 3p1. Aluminum is found in the first space of the third row of the p-block (columns 13-18)... See full answer below. Some are hard to memorise (or predict), so what is the electron configuration of an atom of Al? Melting point ... Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties. The electron configuration for aluminum is 1s 2 2s 2 2p 6 3s 2 3p 1 .

(The condensed electron configuration of aluminum is [Ne] 3s2 3p1.) Therefore the Aluminium electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 1. Accordingly, the combined first three ionization energies of aluminium are far lower than the fourth ionization energy alone. Electron configuration The arrangements of electrons above the last (closed shell) noble gas. Electrons have a specific form of distribution (or configuration) in every atom, even Aluminum.

Video: Aluminium Electron Configuration Notation The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

[16] The electron configuration of aluminum is 1s2 2s2 2p6 3s2 3p1.

In aluminum the configuration of the three outer electrons is such that in a few compounds (e.g., crystalline aluminum fluoride [AlF 3] and aluminum chloride [AlCl 3]) the bare ion, Al 3+, formed by loss of these electrons, is known to occur.

In the case of Aluminum the abbreviated electron configuration is [Ne] 3s2 3p1. Nevertheless, check the complete configuration and other interesting facts about Aluminum that most people don't know.
