AtomicTiles vs Rutherford and the Atom

Introducing Atomic Tiles: an Exploration of Atoms and Molecules, designed by Dr. Seth Bush, Assistant Professor, Department of Chemistry, Cal Poly University, specializing in Chemical Education and developed by Dr. Fred Ventura, Ventura Educational Systems. Atoms are nature's building blocks. Everything is made of atoms. Atomic Tiles is an active learning tool where students explore how atoms come together to form molecules. Using Atomic Tiles students begin to understand the structure of atoms. Students learn that an atom has a dense inner core called the nucleus that contains protons and neutrons. The outer layer of an atom contains the electrons called the electron cloud. Most chemical properties properties of atoms, including how atoms bond to one another, are the result of the outermost electrons in the 'electron cloud' known as valence electrons. Atomic Tiles depicts valence electrons as open or closed circles, similar to Lewis Dots. Open circles are electrons that can be shared to form bonds. Closed circles are electrons that are not shared.

In the early 20th century scientists wanted to know more about atoms. They knew that atoms were electrically neutral and that for every negative particle there must be a positive particle. The scientist Ernest Rutherford made a massive contribution to our understanding of the nature of matter by suggesting a model which fitted experimental data. ---------------------------------- This app forms a companion to GCSE level / High School Physics for Students and anyone interested in the fascinating experiment that shaped our current understanding of the structure of the atom. An ideal revision aid, or classroom demonstration, Rutherford and the Atom will entertain and teach.
