The metalloids have properties of both metals and nonmetals.
Semi-metals, also known as metalloids, have properties of both metals and non-metals. They can conduct electricity to a certain extent like metals but also exhibit non-metallic properties like brittleness. This dual nature makes semi-metals important in various technological applications and in filling the gap between metals and non-metals in the periodic table.
Elements that have properties of both metals and nonmetals are classified as metalloids. Metalloids have properties that are intermediate between metals and nonmetals, such as being able to conduct electricity but not as effectively as metals. Examples of metalloids include silicon and arsenic.
non metals give acidic oxides e.g S,Cetc
An element that has properties of both metals and non-metals is called Metalloid. Example is Germanium.
