MOLECULAR NATURE OF MATTER

Introduction
MOLECULAR NATURE OF MATTER
The scientific atomic theory is credited to John Dalton. Atomic theory is not the end of quest, but beginning. Atoms consists of nucleons and electrons. The nucleus itself is made up of protons and neutrons. The protons and neutrons are again made up of quarks. Quarks may not br the end of the story. There may be string like elementary entities.

PARTICLE NATURE OF ELECTROMAGNETIC RADIATION: PHOTO ELECTRIC EFFECT

Particle Nature of Electromagnetic Radiation:  Planck’s Quantum Theory The important postulates of quantum theory proposed by Max Planck are: 1. Atoms and molecules could emit or absorb energy not in a continuous manner, but discontinuously  in small packets of energy called quanta or photons.  2. The energy (E ) of each quantum of radiation is proportional to its frequency (ν). It is expressed by the equation, E = hν Where ‘h’ is known as Planck’s constant and its value is 6.626×10–34 J s. Photoelectric effect It is the phenomenon of ejection of electrons by certain metals (like potassium, rubidium, caesium  etc.) when light of suitable frequency incident on them. The electrons ejected are called photoelectrons.  This phenomenon was first observed by H Hertz. The important characteristics of photoelectric effect are: 1. The electrons are ejected from the metal surface as soon as the beam of light strikes the surface. i.e.,  there is no time lag between the...
