Refer to table below for the Electrical properties ofĪluminium Heat and Conduction Properties Thermal ConductivityĪluminium Magnetic Properties Magnetic Type The SI unit of electrical conductivity is siemens per metre (S/m).Īluminium is a conductor of electricity. It represents a element's ability to conduct electric current. While Electrical conductivity is the reciprocal of electrical resistivity. Hardness of Aluminium - Tests to Measure of Hardness of Element Mohs HardnessĮlectrical resistivity measures element's electrical resistance or how strongly it resists electric current.The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). Refer to below table for Aluminium Physical Properties DensityĢ.7 g/cm3(when liquid at m.p density is $2.375 g/cm3) Emission spectrum of Aluminium Absorption spectrum of Aluminium Aluminium Chemical Properties: Aluminium Ionization Energies and electron affinity They are widely used to determine the physical conditions of stars and other celestial bodies that cannot be analyzed by other means. Several elements, including helium, thallium, and caesium, were discovered by spectroscopic means. Spectral lines are highly atom-specific, and can be used to identify the chemical composition of any medium. A spectral line may be observed either as an emission line or an absorption line. Spectral lines are the result of interaction between a quantum system and a single photon. Spectral lines are often used to identify atoms and molecules. Spectral Lines of Aluminium - Atomic Spectrum of AluminiumĪ spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from an excess or deficiency of photons in a narrow frequency range, compared with the nearby frequencies. Aluminium atomic radius is 118 pm, while it'sĬovalent radius is 118 pm.
