WebMar 18, 2013 · Metalloids tend to be lustrous, brittle, semiconductors with other properties intermediate between metals and nonmetals. Nonmetals are dull/matte, brittle, and poor conductors of electricity and heat. All of these properties require a visible solid (or liquid) sample to assess, and thus astatine is impossible to assess and classify. WebSilicon, along with boron, carbon, germanium, arsenic, selenium and tellurium are classified as semi-metals or semiconductors. This is because if the appropriate amount of energy is …
