Metals and Non-metals CHAPTER3 In Class IX you have learnt about various elements.You have seen that elements can be classified as metals or non-metals on the basis of their properties. Carbon is a non-metal.It is found in many forms such as charcoal,coke,graphite and diamond.The pencil of lead is a form of carbon called graphite.Carbon is brittle. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Question 4 Why graphite is used in making electrodes? They break easily. Syllabus. All metals are ductile. 7)Hardness:Most of the non-metals can be cut into pieces with a knife. Non-metals are soft except except diamond. 2. not malleable or ductile, usually brittle; lower density (when compared to metals) lower melting point and boiling points (when compared to metals) gains electrons in reactions; This is a list of the nonmetal elements in order of increasing atomic number. Non-metals occupy the upper right-hand portion of the periodic table.Considering the properties of non-metals it is not shiny, malleable or ductile nor are they good conductors of electricity. Required fields are marked *, The property due to which non-metals break on hammering is called. Question 1 Why non-metals are not malleable? Credit: Sheba via WikiCommons CC BY-SA 2.0 Metals make up the vast majority of elements on the periodic table. All metals are ductile b All non metals are ductile c Generally metals are ductile d.some metals are ductile Ans . Examples of metals that are not very ductile include tungsten and high-carbon steel. Conduction: They are poor conductors of heat and electricity. For metals, the chemical bond is called the metallic bond. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture. Last Updated on March 20, 2019 By Mrs Shilpi Nagpal 1 Comment. Advertisement Remove all ads. For Ex:Sulphur,coal,phosphorus etc are non-metals and do not conduct electricity and heat. Sulphur is also a non-metal.If we hammer a piece of sulphur,it will break into small pieces.Sulphur is brittle. Usually, nonmetals mostly located on the right side of theperiodic table. The two most common chemical bonds for ceramic materials are covalent and ionic. toppr. Examples: Most metals are good examples of ductile materials, including gold, silver, copper, erbium, terbium, and samarium. and is also a good conductor. Q3: Boojho has learnt that non-metals on beating with a hammer are generally broken into pieces. a. False. Ductile definition, capable of being hammered out thin, as certain metals; malleable. True. Metals, in contrast, have more homogenous structures and their properties are more easily reconciled.
