In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons.
What is metal and example?
Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel.
Uses of metals: Uses for Metals and Nonmetals: A metal's use is directly linked to its qualities. For example:
Nonmetals are plentiful and useful. These are among the most commonly used:
Different Types of Metal are as follow:
This is hands down the most common metal in the modern world. Steel, by definition, is simply iron (the element) mixed with carbon. This ratio is usually around 99% iron and 1% carbon, although that ratio can vary a bit.
This is the basic steel, good ‘ol carbon and iron, although some other very small amounts of other elements might be added.
Think of it as genetically modified steel. Alloyed steel is made by adding other elements in the mix. This changes the properties and essentially makes the metal customizable. This is an extremely common type of metal because it’s generally still very cheap to make.
Technically this is a kind of alloy steel, but there are so many types in such massive quantities that it usually gets its own category. This is the steel that is specifically focused on corrosion resistance.
Iron (Wrought or Cast):
Even though this is a super old-fashioned metal (especially common during the “iron age”) it still has a lot of modern uses.
As far as metals go, this is a really modern one. Aluminum was first made in 1825, and since then it’s been the foundation for some massive accomplishments.
Magnesium is a really cool metal. It’s about 2/3rds the weight of aluminum, and it has comparable strength. It’s becoming more and more common because of this.
Copper is another old-fashioned metal. Today you’ll see it often as an alloy (more on that later) or in a reasonably pure state.
Brass is actually an alloy of copper and zinc. The resulting yellow metal is really useful for a number of reasons.
This is made primarily with copper, but it also contains around 12% tin. The result is a metal that’s harder and tougher than plain copper.
This is an interesting metal because of how useful it is. On its own, it has a pretty low melting point which makes it very easy to cast. The material flows easily when melted and the resulting pieces are relatively strong. It’s also very easy to melt it back down to recycle it.
This is a really amazing modern metal. It was first discovered in 1791, first created in its pure form in 1910, and first made outside of a laboratory in 1932.
Tungsten has the highest melting point and the highest tensile strength of any of the pure metals. This makes it extremely useful.
Nickel is a really common element that’s used all over. Its most common application is in making stainless steels, where it boosts the metal’s strength and corrosion resistance. Actually, almost 70% of the world’s nickel is used to make stainless steel.
This is a metal that has been used for a long time to make blue pigment in paints and dyes. Today, it’s primarily used in making wear-resistant, high-strength steel alloys.
Tin is really soft and malleable. It’s used as an alloying element to make things like bronze (1/8th tin and 7/8ths copper). It’s also the primary ingredient in pewter (85-99%).
Technically speaking, silicon is a metalloid. This means that it has both metallic and non-metallic qualities.
