The Reactivity Of Metals And Their Discovery

1791 words - 7 pages

Metals are elements that have certain properties and react with several different things. Some metals react with oxygen, some with water, some with hydrochloric acid, and several other things. Also, some elements react more readily than others, and they react at different speeds. Many metals are good conductors of heat and electricity, and they are malleable and ductile. Malleable means that the metal can be formed into a certain shape and it will stay in the same shape, and ductile means that they can be formed and shaped into wires. Metals are solids (except for mercury and gallium), and they tend to be very strong and can hold big masses and weights.Now, in 1869,a man by the name of Mendeleev classified the metals and other elements into what is now known as the Periodic Table. He classified them into eight groups and a section called the Transition Metals. In Group I, these are the most reactive elements; there are mostly all metals except for Hydrogen. In Group II, there are only metals, and then there are the Transition Metals, which are, of course, only metals. In Groups III and IV, there are a few metals, and there are two in Group V and one in Group VI. As the numbers of the groups get higher, the less reactive the metals are.The first metals were discovered in 5000 B.C. These metals were Gold and Copper. Both of which are in the Transition Metals, in the group called VIII B. Gold was discovered first by somebody who remains unknown. How it was found, we don't know either, but we believe that it was found on the ground in little nuggets of gold, in sand or on a riverbed. Gold is found as a native element, which means that it is found in its original state, not in a compound. This is because it is not reactive; it doesn't react with air, water, or hydrochloric acid. Because it was found as a native element, there was no need for extraction in order to find it. Gold was used for making ornaments and jewelry since it was very malleable and easily shaped. Many peoples used it for decorations such as the Egyptians and Etruscan people. Because it is non reactive, it was a good metal to use for these types of things. Also, that is probably why it was the first metal to be discovered.The next metal to be discovered, though in the same year, was Copper. Unlike Gold, Copper is not found as a native element. It has to be extracted from its minerals, and so because of this, it was the first metal to be extracted from its minerals. To extract Copper from its ores, you need moderately high temperatures and carbon. Both of these things are found in campfires and pottery kilns, both of which had been being used for the last thousands of years. In some areas, there was a blue-green rock, which, when there was a campfire or kiln near it, the Copper would be extracted from it and drop to the bottom of the kiln or campfire. After a while, people began to make connections between the rock and the Copper droplets. This was when Copper was discovered.Because...

The Properties of Tradition Metals Essay

1124 words - 5 pages Transition metals are a group of metals that are considered dense and have high melting and boiling points. They are located between the alkaline earth metals group and the boron group. The transition metals are characterized by the number of inner energy levels that are occupied by the atoms. They are then separated into 2 groups: d-type transition metals and f-type transition metals. D-type transition metals are mostly consisted of important

Before this, the only way to look at bones was to cut the
