OK - the first serious, if somewhat simplified answer:
Alloying - the blending of metals. The blending of metals can produce characteristics of the ideal metal, which as it happens, does not exist. Metals can be selected for their resistance to corrosion, for their strength and lightness. None have all of these attributes.
Take for example titanium. This metal is highly resistant to corrosion and very light. It's one flaw is that it is "notch-sensitive". This means that any flaw in the construct, such as a bubble or scratch, pre-disposes the metal to fracture at unreasonably low loads. However, adding the elements aluminum and vanadium produces an ideal metal for medical grade implants, such as spinal fusion plates and prosthetic joints. The particular alloy of choice for this purpose is Ti6Al4V - 90% titanium, 6% aluminum and 4% vanadium.
Also, the temperature at which a metal or alloy is treated (forged, drawn, cast or pressed) has bearing on its characteristics.
Hope this helps

umm, you are having problems answering this?
Do you have any metal in your house? Are those metal objects useful or not? Can you think of anything else metal?
In the time it takes to put this question on here and then wait for an answer, you could have done your homework, watched Sex in the City for an hour and sent 200 instant messages....

Well, there was the bronze age; the Greeks made nice bronze swords and axes. In combination with gun powder, lead became great for bullets, steel for knives and armor.All that armament was great for advancing the armies on the enemy. Then metallurgy improved and they made tanks, airplanes and, cars, and the killing is going strong to this day. So, I'd say we have come a long way baby boomer!

It's easy, just answer this question: If I had to choose one, would I rather be alive in the Stone Age or the Iron Age?
