Answer 2

➢ Metalloid

• Metalloid , also known as semi-metal (semimetal), interposed between the metal and non-metallic material.

A metalloid is an element whose external appearance exhibits the characteristics of a metal, but chemically, it exhibits both metallic and non-metallic properties. For example, arsenic and antimony, which are hard crystalline solids, are obviously metallic in appearance, but when chemical reactions are carried out, they exhibit two different properties, metallic and non-metallic. Some of their oxides are soluble in both acid and alkali. This is called amphoteric nature, because their properties are like alkali and acid. There are many elements that can also generate amphoteric compounds. However, only when the duality of this chemical property is very obvious and at the same time shows the appearance of the metal can this element be called a metalloid.

➢ Basic introduction

These elements are generally brittle and have a metallic luster. Semi-metals usually include boron , silicon , arsenic , antimony , tellurium , and polonium . Although their physical and chemical properties are still poorly understood , they are generally included in semi-metals. Germanium and antimony , which are usually considered metals , can also be classified as semi-metals .
