Humans probably began to combine these substances before history was recorded. We know that humans began combining Metals (copper and tin) about 5,000 years ago to create a flexible metal called bronze. The invention of bronze was an important event, as it made it possible to produce a huge variety of new tools, weapons, and armor.
It is a bronze alloy (a combination of many metals and other elements) and alloys were used as raw materials in construction and trade. Over the past few hundred years, a combination of different elements has led to the production of stainless steel, light aluminum, foil, and other very useful products. At present, synthetic chemical compounds have also transformed the food industry.
The combination of different elements has made it possible for humans to prepare cheap and flavorful food and preserve it for a long time by using chemical preservatives. Chemical compounds are also used to create a wide range of edible tissues from crisp to chewy and soft. Synthetic chemical compounds have also had a profound effect on the pharmaceutical industry.
By combining active and inactive Chemicals in pills, researchers and pharmacists can now produce the drugs needed to treat a variety of disorders.
