Elements use in our Daily Life
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.

Answers:pretty much everything you can think of in life relates to chemistry. think about the clothes you wear, the food you eat, the car you drive, the books you read, the medicines you take, your computer, the weather... everything in this universe is made up of atoms, atoms are made up of protons, neutrons, and electrons. the reactions that take place in your body both to keep you alive (mitosis has chemical processes) as well as sustain you (digestion is all about breaking complex molecules into smaller molecules which can be absobed... all by chemical processes) are all at the most basic level chemistry.
Answers:You can not image any thing without use of chemistry.Say for medicines, petrochemicals and fertilisers ( Made up of crude oil and natural gas or any other C-H compound), Inorganic Chemistry is used for metals and its derivatives a long list of such items.Organic Chemistry just we cannot image. and the derivatives from this like soap, cosmetics,medicines,furniture, switchs,power, cells, circuits,cables,insulation,pipes, -------
Answers:I was a chemistry major for two years in college, now a much happier geology major. Advantages - We have been able to synthesize new materials that make our lives much, much easier. Take polyethelene, for example, you can wear it, you can make it into machine parts, or tools, or you can use it hold last nights leftovers! Chemistry has allowed us to synthesize new medications that change lives (aspirin and birth control, anyone?) They allow us to create new ceramics that absorb heat in a way that allows them to withstand high temperatures and still not burn our hands when we touch them (ps, they're on the space shuttle!) They allow us to understand what makes up our food, our bodies, and our surroundings. We are learning to understand how our world works at the molecular level with chemistry. It's a very cool thing. Disadvantages- While scientists' aim to improve the quality of life for humans, plants, animals, and to save the the environment, sometimes these are interpreted as quick fixes to real issues in society and our world. Any introduction or removal of a chemical in an environment can change the way a system works. (be it social, human, animal, or earth-wide) Repeated experiments on manufacture, testing, use, and long term effects of chemicals are essential to our survival. Look what happened with DDT, CFCs, hormone replacement therapy, and the Bhopal Disaster. While we learned a lot, there was a tremendous cost to the environment and/or humanity. We need to understand what we are really doing with our technology before we implement it. There is no such thing as a magic pill to save us all, unfortunately. So the science of chemistry is good, but what we do with it can harm or help us.
