Which of the following elements is a metalloid?
D. arsenic Weegy:
Elements that are classed as metalloids are Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te), [ and Polonium (Po).
The six elements commonly recognised as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. Other elements less commonly recognised as metalloids include carbon, aluminium, selenium, polonium and astatine. On a standard periodic table all of these elements can be found in or near a diagonal region of the p-block, having its main axis anchored by boron at one end and astatine at the other. Some ...
