Question: Metals, Non-metals, and Metalloids.
Answer: Metals, nonmetals, and metalloids have very relative properties. All known metals have a high boiling and melting point, are typically very dense, thermally and electrically conductive, brittle, have a tendency to lose and gain electrons, and are known to react with acids and copper(II) chloride. Nonmetals are typically volatile, have low melting and boiling points, low density, brittle or soft as solids, low thermal and electrical conductance, and do not react with acids or copper(II) chloride. Metalloids are very much the hybrid of the two classes. They tend to have low boiling points and are not very conductive while others have high boiling and melting points and are extremely conductive. Each group comes in vast categories of elements and has its own special uses....(short extract)
