Atomic Theory
The main principles of atomic theory:
1) All matter is made up of tiny particles called
atoms
2) Atoms are made up of even smaller particles
called protons, neutrons, and electrons
3) Atoms can be distinguished from each other by
their number of protons, neutrons, and electrons
4) A set of atoms, each of which has the same
number of protons, is called an “element”
5) Atoms combine to form molecules
Bohr Rutherford Diagrams
A way of representing atoms
 “shells” represent areas in which electrons
are likely to be found
Each shell can contain a certain number of
electrons
 1st shell- 2 electrons
 The rest- 8 electrons
Electrons are added in a particular order to
the diagram
Atom Building Project
Build a 3-D model of an atom that includes
 Number of protons, electrons, and neutrons
 Nucleus
 Electron Shells
 Correct number of electrons in each shell
If you are in partners build 2!
BE CREATIVE!!!
Ideas!!
For the Rest of the Period…
1. Use your Ipads to research ideas for
your project
2. Discuss who will bring what
3. Pick your element
4. Draw your Bohr-Rutherford Diagram
5. Begin building if possible
