Compare semiconductors with both metals and nonmetallic in terms of their ability to conduct electricity, and state where semi conductors are located on the periodic table

In metals electrical resistivity increases with temperature. Semiconductors conduct like metals above a critical temperature and do not conduct below that temperature. Non-conductors do not electricity. Non-metals do not conduct like metals, for example, carbon as graphite conducts electricity and gets better (resistivity decreases) with increasing temperature.
