state what are metalloids name the metals reorganized as metalloids compare the properties of metalloids with those of these metals state the uses of three different metalloids
Answers
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is neither a standard definition of a metalloid nor complete agreement on the elements appropriately classified as such. Despite the lack of specificity, the term remains in use in the literature of chemistry.

Answer:
a) Metalloids are a very small group of elements found in the periodic table of elements along the zig-zag line that distinguishes metals from non-metals and is drawn from between boron and aluminum to the border between polonium and astatine.
b) The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.
c) Metalloids neither possess a too high or too low value of electronegativity. Metals show ductility and malleability. Non-metals do not show ductility and malleability. Metalloids also do not show this property
d) Metalloids are usually too brittle to have any structural uses. They and their compounds are used in alloys, biological agents, catalysts, flame retardants, glasses, optical storage and optoelectronics, pyrotechnics, semiconductors, and electronics.
