Atomic Structure—Models
Atom Model
This large, colorful, 3-D model is the perfect visual aid for your discus- sions about the atom. Removable pieces will help you illustrate the basic differences between electrons, protons and neutrons—the building blocks of the atom. Stimulate hands-on learning by passing the soft, resilient foam model throughout the class so each student will gain a clear understanding of the make-up of atoms. This versatile model can be used to show how ions form, why electron energy orbitals exist, and even chemical bonding. More advanced classes can take advantage of the graphical images of quarks and the wave nature of subatomic particles to further enhance their knowledge of the modern vision of the atom. 24-page instruction guide provides an extensive historical background of the atom and suggested activities.
Atomic Orbital Model Set
Build 14 basic s, p and d atomic orbitals with this colorful, three- dimensional model set. Use the pink and purple pear-shaped models to represent the lobes of the p and d atomic orbitals. Represent atomic nuclei with opaque white spheres. Each model comes with its own colorless transparent base for display purposes. Set contains 14 easy- to-assemble atomic orbitals—one 1s, one 2s, three 2p, five 3d, one unit with one 2s plus three 2p orbitals as well as one each of an sp, sp2 and sp3 hybrid orbital. Components are of durable plastic for years of demonstration and display. Approximate model heights including base range from 5–9 cm. Instruction sheet and a plastic storage case are included.
Wire-Rimmed Counting Chips
Wouldn’t it be easier to teach chemistry if there were life-size electrons and atoms that students could actually see and touch? Wire-rimmed counting chips are the next best thing! These colorful, transparent discs make perfect, cost-effective models and can be used to represent atoms, molecules, ions, electrons...you name it! Teach the law of conservation of matter and balancing equations—the chips are a great atom-account- ing mechanism. Teach bonding and Lewis dot structures—the chips are ideal representations of electrons. Great for overhead demonstrations! Clean up quickly with the magnetic wand (AP4584) which is the perfect companion for these chips. 100-piece bag; assorted colors.
Magnetic Wand
This sturdy plastic wand contains a powerful bar magnet that quickly and easily picks up iron filings or other magnetic materials. Use this magnetic wand to swipe up wire-rimmed chips when teaching about atoms and balancing equations or when exploring the topic of magne- tism. Cleanup of metal filings has never been easier! Brightly colored.
Never Trust an Atom Mug
