Importance Of Metals In Daily Life

IMPORTANCE OF METALS IN DAILY LIFE Chemical Properties MetalsNon metals usually throw 1-3 electrons in their outer shell. Lose their valence electrons easily. direct oxides that be basic. Are redeeming(prenominal) reducing agents. beat rile off electro negativities. Usually have 4-8 electrons in their outer shell. Gain or make out valence electrons easily. Form oxides that atomic summate 18 acidic. Are good oxidizing agents. Have higher electro negativities. somatic Properties MetalsNonmetals Good electrical conductors and heat. Malleable - plenty be beat out into thin sheets. Ductile - can be stretched into wire. Possess metal(prenominal) luster. Opaque as thin sheet. unshakable at direction temperature (except Hg).Poor conductors of heat and electricity. Brittle - if a solid. Non ductile. Do non possess metallic luster. Transp arnt as a thin sheet. Solids, liquids or gases at room temperature. Metals be very useful. Ores are by natu re occurring rocks that contain metal or metal compounds in capable amounts to make it worthwhile extracting them. For example, exhort ore is used to make iron and steel. Copper is easily extracted, scarce ores rich in cop are becoming much difficult to find.

Aluminum and si are metals with useful properties, only they are expensive to extract. nearly everyday metals are mixtures called alloys. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the some other elemental substances. Metals are used in: emigra tion -- Cars, buses, trucks, trains, ships, ! and airplanes. Aero topographic point -- Unmanned and manned rockets and the space shuttle. Computers and other electronic devices that require conductors (TV, radio, stereo, calculators, security devices, etc.) Communications including satellites that await on a tough but light metal shell. fodder processing and preservation -- Microwave and conventional ovens and...If you emergency to get a full essay, order it on our website: OrderCustomPaper.com
