Some metallic and some non-metallic.\nLike Silicium... it it shiny, just like metals, but doesn't conduct electricity, just like non-metals.\nOr Carbon... it is not shiny and doesn't react with acids, like non-metals, but conduct electricity, like metals.

I think you mean the covalent chemical bonds seen in metals.\n\nThey give metals their ductile and malleable properties...that is they can be stretched into wires and pounded into shapes.\n\nSuch exampels would be gold, sodium, silver and copper.\n\nThese are much different than the ionic bonds found in salts.  Metallic bonds are very covalent, that is, they share electrons among nuclei.  This allows for nuclei to "slide" by each other...macroscopically this is the maleability and ductility.  The sharing of electrons also means electrons can flow easily, and thus metals are good conductors of electricity.\n\nIonic bonds have an electron transfer from one nuclei to another, and are much more rigid in their orientation (leading to brittle materials).

Chemical properties of matter are those that relate to how the substance changes in composition or how it interacts with other substances.\nSome examples of chemical properties are: \npaper burns \niron rusts \ngold does not rust \nwood rots \nnitrogen does not burn \nsilver does not react with water \nsodium reacts with water \nIn each of these, the substance's chemical property is its tendency to:\nreact \ntarnish \ncorrode \nexplode

nonmetals have much higher ionization energies than metals do. this is because non-metals have more protons in their nucleuses to attract their electrons with. metals do not have as many, as compared to the rows they are in, so the electrons will move away from the nucleus of the metal if given a little push.

Maleable and formatable\nand\ngood insulators. They both are properties of metals, which are bonded.\n\nStiff,viscous, and brittle are descriptions of an ionic bond like, for example NaCl, salt.

Copper is a pure metal. The conductivity of metals increase with temparature owing to decrease in the vibration of the +ve ions in the crystal lattice. Germanium is a semiconductor. Its conductivity decreases with temparature. Hence copper has more conductivity than Ge at low temps.

jtkeel is mostly right, except the structure of copper is not crystaline.  Al3K is right about the structure of copper, which is the basic structure of all metals and is what gives them their physical characteristics, like their malleability, conductivity and so forth.

An alloy is a combination, either in solution or compound, of two or more elements, which has a combination of at least one metal, and where the resultant material has metallic properties. The result is a metallic substance with properties different from those of its components.\n\nIn chemistry, a physical change is when a substance undergoes some form of change that does not change the substance at the molecular level (i.e. a chemical change). Physical changes do not create new substances, as in a chemical change, but result in the same substance in a different form or shape. A physical change in which a substance changes states between solid, liquid and gas is called a phase change. When water is frozen into ice it undergoes a phase change, and thus a physical change, as it is still water but in a different form. Under normal conditions physical changes can generally be considered reversible, however this does not always hold true.\n\nA chemical change is a process in which reactants are changed into one or more different products. A chemical change occurs whenever new compounds are formed or existing compounds decomposed. During this reaction, chemical bonds between atoms are broken and new chemical bonds formed. This results in a rearrangement of the chemical bonds.\n\nCONCLUSION/ ANSWER to you question!\nThus, brass, an alloy of copper and zinc, will still have individual copper and zince molecules, there is no change at the molecular level. No new compound has been formed. \nSo alloy undergoes PHYSICAL CHANGE!

You should recognize that, when they combine with nonmetals, metals tend to LOSE electrons and form POSITIVE ions. Nonmetals, on the other hand, tend to GAIN electrons and form NEGATIVE ions.\n\nGet an "A".

PROPERTIES OF METALS\n\nThis section is devoted primarily to the terms used in describing various properties and characteristics of metals in general. Of primary concern in aircraft maintenance are such general properties of metals and their alloys as hardness, brittleness, malleability, ductility, elasticity, toughness, density, fusibility, conductivity, and contraction and expansion. You must know the definition of the terms included here because they form the basis for further discussion of aircraft metals.\n\nHardness\n\nHardness refers to the ability of a metal to resist abrasion, penetration, cutting action, or permanent distortion. Hardness may be increased by working the metal and, in the case of steel and certain titanium and aluminum alloys, by heat treatment and cold-working (discussed later). Structural parts are often formed from metals in their soft state and then heat treated to harden them so that the finished shape will be retained. Hardness and strength are closely associated properties of all metals.\n\nBrittleness\n\nBrittleness is the property of a metal that allows little bending or deformation without shattering. In other words, a brittle metal is apt to break or crack without change of shape. Because structural metals are often subjected to shock loads, brittleness is not a very desirable property. Cast iron, cast aluminum, and very hard steel are brittle metals.\n\nMalleability\n\nA metal that can be hammered, rolled, or pressed into various shapes without cracking or breaking or other detrimental effects is said to be malleable. This property is necessary in sheet metal that is to be worked into curved shapes such as cowlings, fairings, and wing tips. Copper is one example of a malleable metal.\n\nDuctility\n\nDuctility is the property of a metal that permits it to be permanently drawn, bent, or twisted into various shapes without breaking. This property is essential for metals used in making wire and tubing. Ductile metals are greatly preferred for aircraft use because of their ease of forming and resistance to failure under shock loads. For this reason, aluminum alloys are used for cowl rings, fuselage and wing skin, and formed or extruded parts, such as ribs, spars, and bulkheads. Chrome-molybdenum steel is also easily formed into desired shapes. Ductility is similar to malleability.\n\nElasticity\n\nElasticity is that property that enables a metal to return to its original shape when the force that causes the change of shape is removed. This property is extremely valuable, because it would be highly undesirable to have a part permanently distorted after an applied load was removed. Each metal has a point known as the elastic limit, beyond which it cannot be loaded without causing permanent distortion. When metal is loaded beyond its elastic limit and permanent distortion does result, it is referred to as strained. In aircraft construction, members and parts are so designed that the maximum loads to which they are subjected will never stress them beyond their elastic limit.\n\nNOTE: Stress is the internal resistance of any metal to distortion.\n\nToughness\n\nA material that possesses toughness will withstand tearing or shearing and may be stretched or otherwise deformed without breaking. Toughness is a desirable property in aircraft metals.\n\nDensity\n\nDensity is the weight of a unit volume of a material. In aircraft work, the actual weight of a material per cubic inch is preferred, since this figure can be used in determining the weight of a part before actual manufacture. Density is an important consideration when choosing a material to be used in the design of a part and still maintain the proper weight and balance of the aircraft.\n\nFusibility\n\nFusibility is defined as the ability of a metal to become liquid by the application of heat. Metals are fused in welding. Steels fuse at approximately 2,500°F, and aluminum alloys at approximately 1, 110°F.\n\nConductivity\n\nConductivity is the
