usually throw 1-3 electrons in their outer shell.
Lose their valence electrons easily.
Form oxides that be basic.
Are good reducing agents.
beat lower electro negativities.
Usually have 4-8 electrons in their outer shell.
Gain or make out valence electrons easily.
Form oxides that atomic number 18 acidic.
Are good oxidizing agents.
Have higher electro negativities.

Physical Properties
MetalsNonmetals
Good electrical conductors and heat.
Malleable - plenty be beaten into thin sheets.
Ductile - can be stretched into wire.
Possess metallic luster.
Opaque as thin sheet.
unshakable at room temperature (except Hg).Poor conductors of heat and electricity.
Brittle - if a solid.
Non ductile.
Do not possess metallic luster.
Transp arnt as a thin sheet.
Solids, liquids or gases at room temperature.
Metals be very useful. Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. For example, iron ore is used to make iron and steel. Copper is easily extracted, scarce ores rich in copper are becoming much difficult to find.



Aluminum and titanium are metals with useful properties, only they are expensive to extract. Most 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 other elemental substances.

Metals are used in:
Transportation -- 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.
Food processing and preservation -- Microwave and conventional ovens and...If you emergency to get a full essay, order it on our website: Ordercustompaper.com
