All elements that occur in nature can be divided into metals and non metals. Metals conduct heat and electricity, are hard, deformable, shiny, etc. Copper, gold, silver tin and zinc are all metals.
All metals are found in the earth, but most are not found in their pure state. Gold, platinum and sometimes copper and silver are found in their pure state. Gold, platinum and sometimes copper and silver are found in their pure states, but most are found as ores.
An ore is a combination of metal and other elements such as oxygen, sulfur and carbon, which are removed by heating the metal, called smelting.
Most of the metals we use are not pure of elemental metals; they are alloys. Alloys are prepared from two or more metals. Copper and tin are mixed to form bronze. Copper and zinc make up brass, used in many musical instruments. Alloys are made by heating up each of the solid metals until they form a liquid. This liquid is then mixed and cooled.
