We will also provide a summary of them with examples. Basis for Comparison Metals Non-Metals Metalloids Meaning The metals which exhibit the highest degree of metallic behaviour is known as metals.
Non-metals are such elements which do not possess any metallic behaviour. Metalloids are such elements, which possess some of the properties like metal, while some like non-metal. Place in the periodic table Metals are placed on the left side of the periodic table.
Non-metals are placed on the right side of the periodic table. Metalloids are placed in the middle of the periodic table. Location in blocks Located in s, p, d, and f blocks. Non-metals is located in s and p blocks. Metalloids are located in p block. Appearance Metals have a shiny appearance. Non-metals have a dull appearance. Metalloids have a shiny and dull appearance. Conductivity Thermal and electrical conductivity is high in metals. It is very low in non-metals.
Thermal and electrical conductivity is good though it is less than metals. Electronegativity Metals have low electronegativity. Non-Metals have high electronegativity. Metalloids neither possess a too high or too low value of electronegativity.
Ductility and malleability Metals show ductility and malleability. Non-metals do not show ductility and malleability. Metalloids also do not show this property. Arsenic, Tellurium, Antimony, Polonium, Tennessine, etc. Metals are the most abundantly found among all elements. Non-metals are less dense as compared to metals. Non-metals are elements which form negative ions anions by accepting or gaining electrons. They generally have 4,5,6 or 7 electrons in their outermost shell so they tend to gain electrons during chemical reactions.
The metalloids are intermediate in their properties between metals and nonmetals. Taking physical properties into consideration, they are more like the nonmetals, but under certain circumstances, contrary to the expected behaviour many of them can be made to conduct electricity.
These semiconductors find their use in computers and other electronic devices. They can have a dull or metallic appearance. In a periodic table, these elements run diagonally. They are usually brittle. They form alloys with metals. They can both gain or lose electrons in a chemical reaction. Due to their unique properties, they find their use as catalysts, biological agents, flame retardants, alloys and semiconductors in industries.
Boron, silicon, germanium, arsenic, tellurium and antimony are some commonly known metalloids. Metalloid, in chemistry, is a term which describes a chemical element forming a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. They are often called semi-metals. Comparison Basis. Metallic properties. The elements which possess the highest degree of metallic behaviour. They do not possess metallic behaviour. They possess the metallic properties partially.
Location in periodic table. Placed on the left side. Placed on the right side. Placed in between metals and nonmetals. Located in s,p,d,f blocks. Anne Marie Helmenstine, Ph.
