Bitesize properties of metals
WebMar 2, 2024 · Semiconductor metals (or metalloids) have a higher number of valence electrons (usually four or more). So, although they can conduct electricity, they are inefficient at the task. However, when heated or doped with other elements, semiconductors like silicon and germanium can become extremely efficient conductors of electricity. Metal Conductivity
