## Detail Page

supported by the National Science Foundation
This Flash interactive activity explores atomic structure at a pace that middle school students can easily understand. It contains 26 animated pages that depict the atomic nucleus and the three primary subatomic particles: electrons, protons, and neutrons. It was designed to give learners a taste of the particles' properties, such as charge and mass, without introducing advanced terminology.

Please note that this resource requires Flash.

#### 4. The Physical Setting

4D. The Structure of Matter
• 6-8: 4D/M1a. All matter is made up of atoms, which are far too small to see directly through a microscope.
• 9-12: 4D/H1. Atoms are made of a positively charged nucleus surrounded by negatively charged electrons. The nucleus is a tiny fraction of the volume of an atom but makes up almost all of its mass. The nucleus is composed of protons and neutrons which have roughly the same mass but differ in that protons are positively charged while neutrons have no electric charge.
• 9-12: 4D/H2. The number of protons in the nucleus determines what an atom's electron configuration can be and so defines the element. An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms. Atoms form bonds to other atoms by transferring or sharing electrons.

#### 11. Common Themes

11B. Models
• 6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
• 6-8: 11B/M4. Simulations are often useful in modeling events and processes.
