Final answer:
Metals that share both physical and chemical properties with nonmetals are known as metalloids, or semi-metals. These elements are found along the dividing line between metals and nonmetals on the periodic table and are valuable in making semiconductors.
Step-by-step explanation:
Metals that share both physical and chemical properties with nonmetals are called metalloids, also known as semi-metals. They exhibit characteristics that are intermediate between those of metals and nonmetals. For instance, metalloids generally have a metallic luster but are poor conductors of electricity and heat compared to metals. Their unique properties make them valuable in the semiconductor industry.
On the periodic table, metalloids are found along the dividing line between metals and nonmetals. This includes elements such as silicon (Si) and germanium (Ge), which are essential for electronics due to their semi-conductive nature. The range of elements classified as metalloids is limited, but their utility in advancing modern technology is significant.
