Half of the distance between two atoms within a single covalent bond. Erbium has no known biological role, and has low toxicity. 0:45. The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train. After 1860, Mosander's terbia was known as erbia, and after 1877, the earlier known erbia became terbia. Erbium is a chemical element with the symbol Er and atomic number 68. Periodic Table of Elements Er - Erbium Erbium Menu. The shorter the wavelength, the greater the scattering. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). But much like light passing through the atmosphere, scattering occurs - photons of light collide occasionally with the chains of glass in the fibre and the light is attenuated, limiting the length of fibre one can use. Atoms of the same element with different numbers of neutrons. 1) You may use almost everything for non-commercial and educational use. Chemical Characteristics. They have an energy gap less than 4eV (about 1eV). The percentage of the world reserves located in the country with the largest reserves. Phosphorus was first made by Hennig Brandt in Hamburg in Germany in 1669 when he evaporated urine and heated the residue until it was red hot. In 1843, at Stockholm, Carl Mosander obtained two new metal oxides from yttrium, which had been know since 1794.
