4/18/2023 0 Comments Aluminum periodic tableThe Metal dissolves readily in sulphuric acid (H 2SO 4) or hydrochloric acid (HCl) under the formation of Al (III) & hydrogen (H 2), and Concentrated Nitric acid (HNO 3) passivates aluminium metal:Ģ Al (s) + 3 H 2SO 4 (aq) → 2 Al 3+ (aq) + 2 SO 4 2- (aq) + 3 H 2 (g)Ģ Al (s) + 6 HCl (aq) → 2 Al 3+ (aq) + 6 Cl – (aq) + 3 H 2 (g) The metal reacts with all halogens to form aluminium (III) halides:Ģ Al (s) + 3 Cl 2 (g) → 2 AlCl 3 (s) (aluminium (III) chloride)Ģ Al (s) + 3 Br 2 (g) → Al 2Br 6 (s) (aluminium (III) Bromide)Ģ Al (s) + 3 I 2 (g) → Al 2I 6 (s) (aluminium (III) Iodide) Lattice constant: 404.97, 404.97, 404.97 pmįace Centered Cubic (FCC) Reactivity of AluminiumĮlectron affinity: 42.5 kJ/mol Nuclear Properties of AluminiumĪluminium reacts with air, and forming a protective layer of aluminium (III) oxide, which prevents further reaction with oxygen.ĭue to its protective oxide layer, It doesn’t react with water, But if the oxide layer is damaged, the metal is exposed to attack, even by water. Sound Speed: 5000 m/s Atomic Properties of Aluminium Molar magnetic susceptibility: 0.21×10 -9 m 3/mol Physical Properties of Aluminiumĭensity: 2.70 g/cm 3 (In solid) 2.37 g/cm 3 (In Liquid at M.P) Mass magnetic susceptibility: 7.8×10 -9 m 3/kg Volume magnetic susceptibility: 0.0000211 Magnetic susceptibility (x mol): +16.5×10 -6 cm 3/mol Thermal conductivity: 237 W/(m∙K) Electrical properties of AluminiumĬritical point (Superconducting point): 1.18 K (-271.97 oC, -457.55 oF) Magnetic Properties of Aluminium Aluminium Electron Configuration Thermal Properties of Aluminium
