It is a synthetic element (an element that can be created in a laboratory but is not found in nature) and radioactive; the most stable known isotope, 270Bh, has a half-life of approximately 61 seconds.
66 Dysprosium -Dy- its highly susceptible to magnetization, it is employed in various data storage applications, such as in hard disks. Dysprosium powder may present an explosion hazard when mixed with air and when an ignition source is present. Thin foils of the substance can also be ignited by sparks or by static electricity. Dysprosium fires can't be put out by water.
Qué sabemos.- El selenio (del griego σελήνιον, resplandor de la Luna) fue descubierto en 1817 por Jöns Jacob Berzelius.
