Erbium Bohr ModelThe number of electrons in each of Erbium's shells is [2, 8, 18, 30, 8, 2] and its electron configuration is [Xe]4f12 6s2. The erbium atom has a radius of 176 pm and a Van der Waals radius of 235 pm. Erbium was discovered by Carl Mosander in 1843. Sources of Erbium include the mineral monazite and sand ores. Erbium is a member of the lanthanide or rare earth series of elements.Elemental Erbium Picture In its elemental form, erbium is soft and malleable. It is fairly stable in air and does not oxidize as rapidly as some of the other rare earth metals. Erbium's ions fluoresce in a bright pink color, making them highly useful for imaging and optical applications. It is named after the Swedish town Ytterby where it was first discovered.


Fluorine is a Block P, Group 17, Period 2 element. Its electron configuration is [He]2s22p5. The fluorine atom has a covalent radius of 64 pm and its Van der Waals radius is 135 pm. In its elemental form, CAS 7782-41-4, fluorine gas has a pale yellow appearance. Fluorine was discovered by André-Marie Ampère in 1810. It was first isolated by Henri Moissan in 1886.
