Description
The “Structure of Atom” (55x90 cm) educational chart provides clear, detailed diagrams and concise explanations depicting the fundamental components and classical models of the atom, making atomic structure concepts accessible in classrooms and labs.
Chart Features
Printed in multicolor on durable, laminated 55x90 cm paper, suitable for prominent display and lasting use.
Illustrates the modern (Bohr) model of the atom:
Central nucleus containing protons (positively charged) and neutrons (neutral).
Electrons (negatively charged) arranged in concentric shells/orbits around the nucleus.
Labels and visually distinguishes key subatomic particles, showing their relative charge, mass, and position within the atom.
May feature historical atomic models for context (e.g., Thomson’s “plum pudding,” Rutherford’s nuclear model, Bohr’s shell model), often accompanied by brief descriptions or timelines.
Generally includes:
Definitions for atomic number (number of protons), mass number (sum of protons and neutrons), and isotopes.
Examples for elements like hydrogen, carbon, and oxygen, listed with their particle composition.
Educational Value
Clarifies abstract atomic structure concepts visually, aiding comprehension for students at secondary and introductory college levels.
Supports teaching about atomic theory, subatomic particles, isotopes, electronic configuration, and periodic trends.
Helps students understand how atom structure underpins chemical properties, bonding, and periodic table organization.
This chart serves as a comprehensive, engaging resource for teaching the basics of atomic structure and subatomic particles.
