They are generally shiny, and only melt at high temperatures. Their shape can change easily and they can be made into wires or sheets without breaking. Metals corrode, as does the gradual wear of iron. Heat and electricity travel easily through metals, which is why it is not wise to stand next to a metal pole during a thunderstorm!

Metals are very important because of their unique characteristics. Usually metals are hard and strong (there are exceptions to this such as sodium. Sodium can be cut by a knife). Mercury is the metal which is in the liquid state.
What type of bond forms between metal atoms?
The type of bond forms between metal atoms is called metallic bonding. Metals release electrons in their outer shells and these electrons are dispersed between metal cations. Therefore, they are known as a sea of delocalized electrons. The electrostatic interactions between the electrons and cations are called metallic bonding.

Both minerals and metals are found in the natural environment.
When were metals first discovered?
Metals are known to human kind for a very long time. There are evidences to prove about metal usage back in 6000 BC. Gold and copper were the first metals to be discovered. These were used to make tools, jewelry, statues etc. Since then for a longer period only few other metals (17) were discovered. Now we are familiar with 86 different types of metals.

On the other hand, metals like gold and platinum are very stable and unreactive. Metals are Malleable and ductile, which allows them to be used for making certain tools. Metals are atoms, which can form cations by removing electrons. So they are electropositive.
What is the difference between metal and steel?
The main difference between metal and steel is that metals are naturally occurring elements that are present in the Earth’s crust, while steel is an alloy made from metal.
Where do metals occur?
As you know, metals occur naturally in the Earth’s crust, so they don’t have to be produced by humans.
How is steel made?
To produce steel, iron ore is mined and then smelted in blast furnaces. This is where impurities such as silica, phosphorous and sulfur are removed from the iron ore, and a controlled amount of carbon is added. To become steel, the carbon must be reduced so that other elements can be added.
Is steel stronger than metal?
Although metal is naturally occurring and can be found in the Earth’s crust, steel is much stronger. For this reason, metal is best when used in jewelry making, decorative projects or surgical implants, due to its malleable nature. Steel is strong and is virtually indestructible, which makes it a great option for structures like skyscrapers, ...
Is steel a metal?
Steel, on the other hand, is an alloy made from iron metal—meaning without metal we wouldn’t have steel. This also means that steel is not technically a metal, but rather a variation of a metal instead.
