Chemistry is the life of sciences
 
  The word chemistry comes from a modification of the word alchemy, which referred to an earlier set of practices that encompassed elements of Chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine.
 Alchemy is often seen as linked to the quest to turn lead or other base metals into gold, though alchemists were also interested in many of the questions of modern chemistry. 
The modern word alchemy in turn is derived from the Arabic word al-kīmīā (الكیمیاء). This may have Egyptian origins since al-kīmīā is derived from the Ancient Greek χημία, which is in turn derived from the word Kemet, which is the ancient name of Egypt in the Egyptian language. Alternately, al-kīmīā may derive from χημεία 'cast together'.
  Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. 
  In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).
  Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds.
 There are two types of chemical bonds: 
 
  1. primary chemical bonds e.g covalent bonds, in which atoms share one or more electron(s); ionic bonds, in which an atom donates one or more electrons to another atom to produce ions (cations and anions); metallic bonds. 
  2. secondary chemical bonds e.g. hydrogen bonds; Van der Waals force bonds, ion-ion interaction, ion-dipole interaction etc.
 
Most common chemistry experience you see in daily life
 
 Food
 
  Ever tried to think why a particular vegetable bears a particular colour and taste? It has been founded that the sunlight is a beam of white light and when it impacts on an object some of them get absorbed while others are reflected back. 
The vegetables that are green are due to the presence of a chemical compound named chromospheres which absorbs all the wavelengths while reflecting the green light. Similarly, the red colour of tomato which is used to judge its quality is a result of a chemical compound known as lycopene.
  Who hasn’t been mesmerized by the fluffiness of cakes that metamorphose from pastry dough to a tasty well-raised bundle of joy? Thanks to the chemical reaction of magic ingredients called baking soda and baking powder!
  The teardrops rolling out from eyes while cutting an onion is due to the chemical reaction that turn the sulphur present in the onion cells to burst and to become a volatile sulphur product, which once released in air causes itching in eyes, resulting in the outpour of teardrops.
 
Our Body
 
  Our body is made up of chemical constituents, present in a number of combinations of various elements – oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
 
 Our Mind
 
  Various emotions we feel are, in fact, a result of chemical messengers i.e. neurotransmitters. Love, jealousy, envy, infatuation and infidelity all find their roots in chemistry.
It is easily observed that the most unobserved and repetitive phenomena that take place in our daily lives are so much entwined in chemical science.  The list may be continued to fill hundreds of pages with the miracles of chemistry in our lives that take place each and every day.
Thus, it is the Chemistry that is responsible for various unnoticed actions and reactions in the universe.
  The daily life chemistry is the theme of science which is all around us every minute in every location and there is not any shortage of examples to prove this fact. Without chemistry, our life is impossible, so it is one medium to live a better life and better doing. So it is a must for everyone to learn and enjoy. Hence effective and good use of chemistry is the need of this modern technological world. For example
 
- Toothpaste, Soap/Detergent
- Food Preservatives 
- Drugs and medicine
- Agriculture
- Oxidation The food we take is oxidized in our stomach and produces energy 
- Industries and transport
- Science and Technology
- Environment Issues
