It is an ionic bond.What we get is an ionic compoundNon-metals react with chlorine to form non-metal chloride. The periodic table comprises an arrangement of elements based on certain chemical properties that they exhibit. Metals form an alloy with other metals or non – metals. The metals are arranged on the left side and the non-metals on the right side of the periodic table. Properties_of_Metals doc, 35 KB. Your books, clothes, pencil, water bottle, bag, table, the door are all examples of non-metals. Only 18 elements of the periodic table are generally considered nonmetals, whereas more than 80 elements are considered metals. They can be beaten into thin sheets. Ph.D(Chemistry), B.Ed, VTU, Karnataka Revision lesson on metals and non metals. Making_Salts ws. Non-metals are positioned on the right side of the periodic table. What we get is a co-valent compound.Only highly reactive metals react with hydrogen to form metal hydride.Table of reactivity series shows order in which the metals are arranged based on their comparative reactivity.Steps Involved In The Extraction Of Metals From The OreIn this process, ores are heated in the absence of oxygen where metal oxide is formed and COIn this process, sulphur ore is heated in the presence of oxygen.
Non-metals are not …………… so, they cannot be made into thin wires. In this calcination, ores are heated in the absence of oxygen where metal oxide is formed and ………………… releases.iv. less reactive metals from its salt solution.vi. The other nonmetals occur mainly as compounds. The worst conductor of heat is lead whereas Iron and mercury are poor conductors of electricity.• Metals are shiny. Generally, metals are in a solid state at room temperature. Exception being diamond and graphite.Poor/ bad conductors of heat and electricity exception being graphite.Comparison Of Chemical Properties Of Metals And Non-metalsMetals on reacting with water form metal oxides or metal hydroxides and release H2 gas.Non-metals cannot give electrons to hydrogen in water to be released as H2 gas. Example: Sulphur and phosphorus.• Non-metals are not ductile so, they cannot be made into thin wires.• Non-metals are insulators or poor conductors of electricity and heat because they do not lose electrons to transmit the energy.• At room temperature, they can be in the state of solids, liquids or gases.• Non-metals generally have somewhere around 4 to 8 electrons in the outer shell.• Non-metals tend to gain or accept valence electrons.• When they are exposed to oxygen, non-metals react with oxygen to form acidic oxides.• Non-metals have high electro-negativity; they are electro-negative elements.Comparison Of Physical Properties Of Metals And Non-metalsSolid at room temperature. Only 18 elements of the periodic table are generally considered nonmetals, whereas more than 80 elements are considered metals. Question 14. Why does calcium float in water? For example, elements such as aluminium, gold, and silver can be beaten into thin sheets for common usage purpose.• Metals are ductile.

Properties of a typical metal (when solid) Metals which are placed on the left-hand side of the periodic table are separated from non-metals by a zigzag line that starts from Carbon (C) and runs down Phosphorus (P), Selenium (Se), Iodine (I), till Radon (Rn). Many metals produce metal oxide by burning in the oxygen of the air. All metals are equally ductile.
