SSC MCQ Question Ans. Structure of Matter. SSC MCQ Question Ans. The structure of Matter. Every matter of the universe is made of small particles. They are so small that they are not even visible with the high-efficiency microscope. The name of the smallest particle of the fundamental element is called atom and the smallest particle of compounds are called molecule. Every atom has its own characteristics. A principal characteristic is its atomic number. Atom and molecule have actual and relative mass. Proton, electron, and neutron are the principal particles of the atom.
SSC MCQ Question Ans. Structure of Matter
Nucleus, at the center of the atom, is composed of proton and neutron which bears the total mass of the atom. Electrons of the same number of proton move around the nucleus on various axis. The same elements again have atoms with different atomic mass which are called isotopes. They have multifarious uses in various fields of human life.
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.
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.
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.
Chemistry is one of the diverse branches of physical science. It is known as the science of life. The practice of chemistry has been in a constant increase since the ancient time. The present-day chemical industries have been evolved from the early practices of the Alchemists. Chemistry as a discipline encompasses a wide range of areas. It has always been devoted to the welfare of human and its environment.
teachingbd24.com is such a website where you would get all kinds of necessary information regarding educational notes, suggestions and questions’ patterns of school, college, and madrasahs.
