Elements use in our Daily Life
We can see all known elements in the long form of the periodic table. They are arranged according to their atomic number which increases from left to right in the periodic table. The chemical and physical properties of elements can be identified on the basis of their position in the table or with the help of their valence shell configuration which can be determined by checking the periodic table only. We can observe several elements in our surroundings also. There are various elements which are involved in different applications and quite useful for us.
Let’s have a look on elements uses in our daily life. You can find iron in nails, Al in coke cans and aluminium foil, Li in watch batteries, Au in microprocessors, Cu in coinage, Zn in galvanised steel, oxygen and nitrogen in air, H in water, Ne in signs, U in power production, S in matches and food preservation, Cr in bright work on cars and P in matches. Carbon is basic of whole of the living world. Each C atom contains 4 electrons in its valence shell and can form 4 covalent bonds with other carbon atoms or other atoms to form different carbon compounds.
Due to catenation property of carbon, there are many known compounds of C compare to any other element. Another well known element is hydrogen which is the lightest element and plays a very important role in chemistry. The combination of carbon and hydrogen results the formation of hydrocarbon compounds which are distributed everywhere.
For example, methane, water, butane etc. are very useful compounds. It is also found in sun, other stars and in interstellar space. The nuclear fusion reactions involve hydrogen as a source of energy in the sun and keep us warm. Oxygen is the most abundant element in the earth’s crust. It is found around 21% in atmospheric air and is essential to life.
It involves in the oxidation processes such as combustion and produces the energy needed for life. It is a highly electronegative element and also a strong oxidizing agent. Similarly nitrogen is found around 78% in atmospheric air but cannot absorb directly by body. It is not one of the most abundant elements and plays an important role in the chemical structure of proteins and nucleic acid. Even plants cannot absorb it directly but an absorbed in the form of various nitrogen compounds. It is one of the essential components for the growth of plants therefore also provide in the form of agricultural fertilizers. Iron and silicon are involved in our everyday life in little different manner compare to theses discussed elements.
We can find many iron equipments, household items in your surroundings. It is 5th most abundant element and has been used as a structural material. Silicon is 2nd most abundant element in the earth’s crust. It is widely used as semiconductors and glass optical fibers for communication.
