What term is given to elements that exhibit properties of both metals and non-metals?

💡 Solution & Explanation

Metalloids are chemical elements such as silicon, germanium, and arsenic whose physical and chemical properties intermediate between those of metals and non-metals. Transition elements are entirely metallic d-block elements, halogens are reactive non-metal elements in group seventeen, and alkali metals are highly reactive s-block metals. These elements play a crucial role in semiconductor technology due to their unique electrical conductivity.
