WebClassify germanium as one of the following: a. nonmetal b. main group metal c. transition metal d. metalloid e. none of the above; Pure silicon is a very poor conductor of electricity. Titanuim, which also possesses four valence shell electrons is a metallic conductor. Explain the differences. How many valence electrons does germanium (Ge) have? WebFeb 15, 2024 · Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. They are not conductors in the metallic sense of the word, but are semiconductors. … Is GE conductive? What are the advantages of Ge and Si as semiconductor? WebApr 25, 2001 · Carbon, silicon and germanium (germanium, like silicon, is also a semiconductor) have a unique property in their electron structure -- each has four electrons in its outer orbital. This allows them to form nice … nuffield health check reviews
