What is the relationship between the reactivity of a metal and the date it was first extracted?
The less reactive a metal is, the more likely it is to be found native in the Earth, or the easier it is to extract. By and large, the reactive metals, which are hard to extract, were discovered later.
What metals were the first to be used during the neolithic age?
During the Neolithic Age, the first metals to be used were copper and gold. These metals were initially hammered into decorative items and jewelry. Later on, people discovered how to extract and work with more durable metals like bronze and iron.
Is carbon the first element discovered?
hydrogen is. that's why it is firstAnswer:While the original elements were fire, earth, air and water the term has evolved to mean specific materials with unique attributes formed of one particular atom.The elements as we know them today were discovered no particular order. THere is no schedule for the discovery. Metals such as gold, silver, lead, copper and iron were among the first as they were found in a pure state in nature and were immediately useful to people. Other elements like sulfur and carbon while not metals are found pure in nature. Even later were elements that needed preparation to separate them from other materials - as an example the gases and reactive metals and non metals. Finally the short lived radioactives and rare gases were identified.

What is the difference between precious metals to metals?
Gold and Silver were some of the early "precious metals" to be isolated. They are relatively rare. Gold is relatively nonreactive and thus maintains a wonderful luster. It also has tremendous workability. Silver is somewhat similar, not as rare as gold, but has a nice luster, and good workability.Other metals such as Platinum and Palladium also are relative rare and non reactive.This would compare to copper which was probably initially isolated in the form of bronze, but later purified. Somewhat more common than the precious metals, and corrodes quickly. Iron and other metals were refined later in our history. It has great strength, but oxidizes quickly.The "Ancients" discovered the beauty and workability of gold and silver, and started using them for currency and jewelery.In recent times, gold and silver have been used in electronics due to their high workability and low resistance, and resistance to corrosion. Yet much of the value still is attributed to the value given by the ancients as "precious".
What metals was used by Neolithic people for tools?
Neolithic people used metals such as copper, bronze, and later iron for making tools. These metals were important advancements in tool-making during the Neolithic period, allowing for more efficient agriculture and craftsmanship.
