“Metals Nonmetals and Metalloids – Periodic Table.” ThoughtCo. The main difference between metals nonmetals and metalloids is that metals show the highest degree of metallic behavior and nonmetals do not show metallic behavior whereas metalloids show some degree of metallic behavior. Most of these elements are used in various applications. Metals, nonmetals and metalloids are elements that are found in the earth. Metalloids:Metalloids have an intermediate value of electronegativity. Nonmetals: Nonmetals show a very high electronegativity. Metals:Metals have a very low electronegativity. Metalloids:Thermal and electrical conductivity of metalloids is good but less than metals. Nonmetals:Thermal and electrical conductivity of nonmetals is very low. Metals: Thermal and electrical conductivity of metals is very high. Metalloids: Metalloids do not show malleability and ductility. Nonmetals:Nonmetals do not show malleability and ductility. Metals:Metals show malleability and ductility. Metalloids: Metalloids have a dull or shiny appearance. Nonmetals: Nonmetals have a dull appearance. Metalloids: Metalloids are found in p block. Nonmetals: Nonmetals are found in s and p blocks. Metals:Metals are located in s, p, d and f blocks. Metalloids: Metalloids are found in the middle of the periodic table. Nonmetals: Nonmetals are found in the right side f the periodic table. Metals:Metals are found in the left side of the periodic table. Metalloids: Metalloids are elements having a low degree of metallic behavior. Nonmetals: Nonmetals are elements showing less or no metallic properties. Metals:Metals are elements having the highest degree of metallic behavior. The number of electrons in the s and p orbitals is a medium number.įigure 4: Position of Metals (Blue), Nonmetals (Red) and Metalloids (Green) in the Periodic Table Difference Between Metals Nonmetals and Metalloids Definition These elements are positioned in between metals and nonmetals in the periodic table. Metalloids are placed in p block in the periodic table. The density of metalloids is in between metals and nonmetals. All metalloids are solids at room temperatures. The major application of metalloids is in the production of semiconductors. Although they are not excellent thermal and electrical conductors, metalloids are capable of conducting heat and electricity. The appearance of metalloids can be either dull or shiny. Metalloids show some metallic properties and some nonmetal properties. Metalloids are elements having a low degree of metallic behavior. Electronegativity is very high in nonmetals. The oxidation number of a nonmetal can be either positive or negative. They tend to form anions by gaining electrons. These elements have a high number of electrons in the outermost s and p orbitals. These nonmetals are included in the s and p blocks. Nonmetals are included in the right side of the periodic table. Therefore, mercury atoms can easily escape, resulting in a lower melting point.įigure 2: Diamond- made out of carbon nonmetal Unlike other metal atoms, mercury atoms are weak at sharing electrons with each other, so they have weak interactions. Although Mercury is a metallic element, it is a liquid at room temperature because all other metals usually have higher melting points. Metals are usually solids at room temperature. Malleability refers to a metal’s ability to deform under pressure and ductility refers to its ability to be drawn into wire-like structures. Ductility and malleability is a main feature of metals. They have a characteristic metallic appearance known as luster or shine. Metals are found in the left side of the periodic table. Metals are elements having the highest degree of metallic behavior. Key Terms: Ductility, Malleability, Metal, Metalloid, Nonmetal What is the difference between Metal Nonmetal and Metalloid This is the main difference between metals nonmetals and metalloids. A metalloid is an element having intermediate properties of both metals and nonmetals. A nonmetal is an element that does not have the properties of a metal. A metal is an element which is typically hard, shiny, fusible, malleable, and ductile, with good electrical and thermal conductivity. Elements are categorized into metals, nonmetals and metalloids according to this classification. However, the major way of categorizing these elements is according to the degree of metallic properties they display. These metals can be classified into different categories according to the similarities in their properties. The periodic table of elements indicates all elements that have been discovered on earth.
