ATOMIC MODELS: The following scientists worked on Atomic Model. 1. J J THOMPSON: proposed a model of Atom consisting of positive and negative charge, present in equal amount so that an atom will be neutrally charged. He proposed that atom was a sphere but the negative and positive charge were embedded in it. ( DIAGRAM LEAVE ABOUT 5 LINES) 2. ERNEST RUTHERFORD: Rutherford reversed the Thompson’s model which he showed with his experiment that atom has a small strong nucleus of positively charged. He stated that atom is composed of empty space mostly with electrons orbiting in a set, predictable paths around fixed positively charged nucleus. ( DIAGRAM, LEAVE ABOUT 5 LINES) 3. NEIL BOHR: His model was based on quantum principle. An atom has a positively charged nucleus, and electron travels in around the nucleus in a specified orbit (DIAGRAM, LEAVE ABOUT 5 LINES) DALTON’S ATOMIC THEORY John Dalton, British Physicist and Chemist propose...
