INTRODUCTION TO PERIODIC TABLE

-

Chemical elements are arranged tabularly in the periodic table according to their atomic number, electron configuration, and recurrent chemical characteristics. The elements are shown in columns referred to as groups or families and rows referred to as eras. Atomic parameters including electronegativity, ionization energy, and atomic radius are shown in the table as periodic trends. It offers a methodical approach to comprehending elemental interactions and forecasting how they will behave in chemical reactions. The first periodic table that was widely used was made in 1869 by Dmitri Mendeleev, and it has since been updated and improved upon with the discovery of new elements. The periodic table is still an essential tool in chemistry today, directing investigations, teaching, and real-world applications across a wide range of scientific domains.

INTRODUCTION TO CHEMISTRY

-
The interesting study of matter, including its composition, structure, and the changes it goes through in different chemical interactions, is known as chemistry. Fundamentally, chemistry is the study of the building components of everything around us, with the goal of solving the secrets of the microscopic world. Chemistry is deeply ingrained in everything we use on a daily basis, including the water and air we breathe, the food we eat, and the gadgets we depend on. Important ideas in chemistry include: Matter is anything that has mass and takes up space. It makes up everything in our environment. Matter is a substance that exists in several states, including solid, liquid, and gas. It may also change chemically and physically. Many disciplines, including environmental science, materials science, industry, and health, depend heavily on chemistry. In tackling global issues like pollution, climate change, and the advancement of new technology, it is vital. Understanding the natural worl...
