Chemistry on Metals Essay

A metal is defined as a chemical element that is malleable and ductile, usually solid, has a characteristic luster, and is a good conductor of heat and electricity, e. g. copper or iron.

Metals form oxides that are basic, they are good reducing agents and metals have lower electro negatives. There are many properties of metals. The chemical properties are that they can combine together with other metals to form am alloy.

The mechanical properties of metals are that they are very strong and ductile which enables the extensive use of metals in structures and machinery.They are malleable and they can be deformed that is they can be turned into different shapes like the aluminum frames for windows. Metals are also very strong and their strength allows them to be the perfect material to use for the construction of buildings, aircraft frames, bridges, gas pipelines and cables. Metals are electrical and thermal conductors. They also have high densities compared to those of non metals. Metals aren’t always very expensive but some metals like platinum are expensive. All metals are extracted from the Earth using mining methods that result in ores which provide a rich source of that particular metal.Metals have amazed mankind for ages including the Before Christ time.

The metals were used back in those times for weapons for purposes such as hunting. Especially silver and gold, which were discovered a long time ago and used by people back then. So basically, gold, silver, iron and copper were the oldest metals discovered around 6000 BC. The growth of metals continued as the time passed and now in the 20th century there are so many metals with so many useful uses for us.

There are many uses of metals, as I mentioned above that metals were used as weapons and tools back in the olden days.Metals such as gold, silver and platinum are also used for making jewelry such as necklaces or rings. Also, ,since aluminum is a light metal it is used to make air craft bodies. Metals such as Iron are used for making cooking vessels and water boilers etc. Since, the metal called copper is a good conductor of electricity, it is used in making cable wires.

Lithium is a metal which is used to make batteries, uranium is a metal that is used in nuclear power stations, lead is used for car batteries, the metal called titanium is used for making cooking materials, nickel is used in coins and chromium is used for making chrome plated items.So as you can see, first the metals had very few and minor uses such for making weapons or tools but as the human civilization has advanced, it is seen that the uses of metals have become very advanced and useful. Metals are also used for plating certain things as they help to prevent corrosion. The existence of metals also provide jobs to many people as there are many products made out of metals and their factories and businesses help employ people and provide them with money. It is a fact that metals are a very important part of our lives.All these above mentioned uses are what make metals very important to us.

Metals are mainly used in transportation that is they are used to make cars, buses, trucks, ships and airplanes and without metals transport would be really difficult. Metals are also used in computers and other electronic devices such as televisions so they also provide us with entertainment which makes metals very important in our everyday lives. Metals also help us to communicate outside space that is through outer space communication.Metals are also used during food preservation that is to make microwaves to preserve our food which overall makes metals very hard to live without and very important to us. There are also many allotropic forms of metals which include diamonds and graphite. Diamond is one of the most expensive metal there is. It is shiny and therefore is used for jewelry purposes. Also, graphite is used in pencils that help us to write.

So, overall metals are very important to us and life would be very difficult without them.
