Is germanium a luster?
It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator.
What is germanium most like?
What element is most similar to germanium? It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon.
Is germanium transparent?
Germanium is transparent to infrared radiation and presents an extremely high dielectric constant (e=16).
Where do you find germanium?
Germanium is primarily mined with zinc ore as well as with argyrodite, germanite, and coal according to the Los Alamos National Laboratory. According to Chemistry Explained, germanium is mined in Alaska, Tennessee, China, the United Kingdom, Ukraine, Russia and Belgium.
What does bromine look like?
Free bromine is a reddish brown liquid with an appreciable vapour pressure at room temperature. Bromine vapour is amber in colour. Bromine has a pungent odour and is irritating to the skin, eyes, and respiratory system. The electron affinity of bromine is high and is similar to that of chlorine.
What makes germanium unique?
Germanium is a lustrous, hard, gray-white semi-metallic element with a crystalline and brittle structure. It is a semiconductor. Germanium and the oxide are transparent to infrared radiation. Germanium also has the unusual property that (like water) it expands as it freezes.
Is germanium transparent translucent or opaque?
Germanium is transparent to infrared radiation and presents an extremely high dielectric constant. Germanium is transparent to infrared radiation and presents an extremely high dielectric constant (e=16). That makes it the best material to produce a high contrast PBG.
