kinetic theory of gases

Kinetic theory of gases The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or Molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container. According to kinetic theory of gases, the molecules of … Read more

chemical bonding and molecular structure

Chemical Bonding and Molecular Structure The smallest particle of element is atom and the smallest particle in a compound is molecule. The force or the binding that keeps the atoms in the molecule combined during the formation of molecule is called chemical bonding. The concepts like that of Kossel-Lewis, VSEPR principle, valence bond theory, molecular … Read more
