SSC EV Chemistry 4th Chapter Note

SSC EV Chemistry 4th Chapter Note. The concept of Chemistry. Chemistry, a branch of physical science, is the study of the composition, properties, and behavior of matter. Chemistry is concerned with the atoms and their interactions with other atoms, and in particular with the properties of the chemical bonds. The chemistry is also concerned with the interactions between the atoms (or groups of atoms) and various forms of energy (e.g., photochemical reactions, changes of phases of matter, the separation of mixtures of polymers, properties, etc).

The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism, and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold.

Alchemy, which was practiced around 330, is the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies (Zosimos). An alchemist was called a ‘chemist’ in popular speech, and later the suffix “-ry” was added to this to describe the art of the chemist as “chemistry”

Chemistry is a branch of science that involves the study of the composition, structure, and properties of matter. Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its change, for instance through chemical reactions.

Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule. Understanding the molecular structure of a compound can help determine the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

The days are long past when one person could hope to have detailed knowledge of all areas of chemistry. Those pursuing their interests into specific areas of chemistry communicate with others who share the same interests. Over time a group of chemists with specialized research interests becomes the founding members of an area of specialization.

The areas of specialization that emerged early in the history of chemistry, such as organic, inorganic, physical, analytical, and industrial chemistry, along with biochemistry, remain of greatest general interest. There has been, however, much growth in the areas of polymer, environmental, and medicinal chemistry during the 20th century. Moreover, new specialties continue to appear, as, for example, pesticide, forensic, and computational chemistry.

This course provides students with the opportunity to develop their knowledge, understanding, and skills in relation to properties and structures of matter and a variety of chemical reactions incorporating organic compounds and acid/base equilibrium reactions.

teachingbd24.com is such a website where you will get all kinds of necessary information regarding educational notes, suggestions and question patterns of schools, colleges, and madrasas. Particularly, you will get here special notes of Chemistry that will be immensely useful to both students and teachers. The builder of the website is Mr. Md. Shah Jamal who has been serving for 35 years as an Assistant Professor of Chemistry at BAF Shaheen College Dhaka. He expects that this website will meet up all the needs of Bengali version learners /students. He has requested concerned students and teachers to spread this website home and abroad.
