An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus of the atom contains the protons and the neutrons. The outermost regions of the atom are called electron shells and contain the electrons. Atoms have different properties based on the arrangement and number of their basic particles. In this lesson students will handle life size atoms to identify the subatomic particles and its properties. Students will also construct ball and stick models of certain molecules.
This lesson involves mostly hands on with atoms. Teacher can choose to use any atom that fits in the scenario. All atoms are available in our IFX library
