Name the major element present in the earth's crust ? What is it used for? (And can you explain me that what we have to write in the second part of question i.e. we have to explain all elements or .. else)
Answers
Answer:The most abundant elements in the Earth's crust are presented below:
Oxygen - 46.6%
Aluminum - 8.1%
Silicon - 27.7%
Iron - 5%
Explanation:
The rigid, top layer of the Earth is called the lithosphere. It consists of the Earth’s crust and the top-most part of the mantle. Most geological activities that affect the Earth take place on the lithosphere. It is the most rigid of all of Earth’s layers. The lithosphere consists of oceanic and continental lithospheres. Oceanic lithosphere consists of Oceanic crust which forms the floors of seas and oceans while continental lithosphere consists of continental crust made of land masses. The Earth’s crust is important as it supports human and plant life and contains elements and such as aluminum which facilitate technological development.
Uses of abundant element
Silicone rubber is used as a waterproof sealant in bathrooms and around windows, pipes and roofs. The element silicon is used extensively as a semiconductor in solid-state devices in the computer and microelectronics industries. For this, hyperpure silicon is needed.
Aluminium is a silvery-white, lightweight metal. It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties.
Uses of iron
It is used to manufacture steel and also used in civil engineering like reinforced concrete, girders etc. Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese
Oxygen is used by animals and plants in the respiration (breathing) process. Tanks of oxygen are used in medicine to treat people with breathing problems. They are also used as life support for astronauts and scuba divers. The majority of the oxygen used in industry is used in the manufacturing of steel.
What are elements
In chemistry an element is a species of atom having the same number of protons in its atomic nuclei. For example, the atomic number of oxygen is 8, so the element oxygen describes all atoms which have 8 protons. In total, 118 elements have been identified.
