Atomic Models

The atom is the smallest particle capable of identifying a chemical element and participate in a chemical reaction. The study of the atom began in ancient Greece with the philosopher Leucippus and his disciple Democritus: for them, the atom was the smallest component of all existing matter. Since then impossible to divide it into smaller parts. The course of history, many scientists and scholars have attempted to define the atom as its form, giving rise to various theories about its physical constitution. There arose the atomic models. How I Designed This These models are very easy to do, the only challenge is to position the components of each model in the correct position to represent the characteristics of each model. Project: Atomic models Objectives Help teachers in the classroom showing students the evolution of atomic models with a physical model is easier for students to identify the differences in each of them. Audiences high school; chemical classes; entrance exam preparation courses; home schooled students; Preparation Students should know a little chemistry and atomic models. Step 1: Research about molecular geometry Step 2: Create the model Model Dalton (billiard ball) - 1803 Thomson model (plum pudding) - 1897 Model Rutherford-Bohr (planetary system) - 1908/1910 Results After printing students should be able to identify the different atomic models and their characteristics.
