What is chemistry how chemistry plays an important role in different fields explain with example?
Chemistry is a very important branch of science. Chemistry is the study of science that deals with constituents of matter like atoms molecules, ions etc.; and its properties, structure, behaviour, and interactions among them. Since everything is made up of atoms and molecules, we can see the chemistry all around us.
What is the importance of chemistry in your field of specialization?
Because it is so fundamental to our world, chemistry plays a role in everyone’s lives and touches almost every aspect of our existence in some way. Chemistry is essential for meeting our basic needs of food, clothing, shelter, health, energy, and clean air, water, and soil.
What is the importance of chemistry in our daily lives?
Chemistry is important because everything you do is chemistry! Even our body is made of chemicals. Chemical reactions occur when we breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it’s the study of everything.
What are the 4 main elements of organic chemistry?
Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements.
What is difference between elements and compound?
Element: Pure substance consisting of one type of atom. Compound: Pure substance consisting of two or more different atoms. Mixture: Two or more different substances not chemically combined.
What is the most essential element to life?
Carbon
What are the 6 major elements of life?
The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulphur and phosphorus.
How do humans use matter and the elements everyday?
Humans use matter and for their everyday lives. -Matter is used by humans for cooking, eating, working and etc. -Element is used by humans to created devices and also to use it in everyday life. For example, you will use Oxygen to breathe.

Do we need elements in our body?
What elements are present in the human body? Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body. 25 elements are known to be essential to life.
How do we use beryllium in everyday life?
Beryllium is used in gears and cogs particularly in the aviation industry. Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.
Is beryllium used in medicine?
Uses for Beryllium in Medicine The special properties of beryllium are essential to medical technologies that save and enhance lives. Improving imaging. Beryllium foil provides the window through which tissue-penetrating x-rays are focused, while maintaining the vacuum inside the x-ray tube generator.
What is an interesting fact about beryllium?
Beryllium is a Group 2 lead-gray colored metal with a very high melting point of 1287 °C (2349 °F). Interesting Beryllium Facts: It is a hard metal, but is brittle at room temperature. Beryllium salts have a sweet taste, and the element was once called glucine with a symbol of Gl due to its flavor.
What makes beryllium unique?
Uniquely strong and light, beryllium is used to make cell phones, missiles and aircrafts. Steel gray in color, beryllium’s modulus of elasticity is about one-third greater than steel. Beryllium is nonmagnetic and resistant to concentrated nitric acid.
How poisonous is beryllium?
Breathing in fumes or dusts of beryllium compounds may injure the lungs. While most commonly associated with diseases of the lungs, beryllium may also affect such organs as the liver, kidneys, heart, nervous system, and the lymphatic system.
How is beryllium created?
Beryllium is most commonly extracted from the mineral beryl, which is either sintered using an extraction agent or melted into a soluble mixture. The sintering process involves mixing beryl with sodium fluorosilicate and soda at 770 °C (1,420 °F) to form sodium fluoroberyllate, aluminium oxide and silicon dioxide.
