WebAtomic Structure of Magnesium Magnesium atomic radius is 145 pm, while it's covalent radius is 130 pm. Atomic Spectrum of Magnesium Magnesium Chemical Properties: Magnesium Ionization Energies and electron affinity The electron affinity of Magnesium is 0 kJ/mol. Ionization Energy of Magnesium Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. Magnesium has the lowest melting (923 K (650 °C)) and the lowest boiling point 1,363 K (1,090 °C) of all the alkaline earth metals. Pure polycrystalline magnesium is brittle and easily fractures along shear bands. It becomes much more malleable when alloyed with small amount of other metals, such as 1% aluminium. The mal… interview writing format igcse
