PPT-The Atom Rutherford’s Model of the Atom

Rutherford proposed that most of the mass of the atom was concentrated at the atoms center Rutherfords Model of the Atom Rutherfords experiment suggested that an atoms positive charge is concentrated in the center of the atom . At the end of this lesson, you need to draw . a diagram for each model showing the evolution of atomic theory:. ". Plum-Pudding" Model. Rutherford . Atom. Rutherford-Bohr . Atom. Charge-Cloud .

This is the Greek philosopher Democritus who began the search . for a description of matter more than 2400 years ago. He asked:. Could matter be divided into smaller and smaller pieces . (around 400 BCE). Democritus thought matter could be divided into. . smaller and smaller pieces until a . single indivisible . particle is reached. . He named this particle the . atom. He proposed that atoms are of different sizes, in constant motion, and separated by empty spaces.. Atomic Models. Do things come from nothing?.
