📖 About This Experiment

Atoms are the fundamental building blocks of matter, consisting of a dense nucleus containing protons and neutrons, surrounded by electrons in orbitals. This experiment visualizes atomic structure for elements 1-20, showing how electrons are arranged in shells around the nucleus.

💡 Key Concepts

  • •Protons: Positively charged particles in the nucleus (determine atomic number)
  • •Neutrons: Neutral particles in the nucleus (add mass without charge)
  • •Electrons: Negatively charged particles in orbitals (determine chemical properties)
  • •Electron Shells: Energy levels where electrons orbit (2, 8, 18... electrons)
  • •Atomic Number: Number of protons (defines the element)

🔢 Key Formulas

Mass Number
A = Z + N
Where Z = protons, N = neutrons
Shell Capacity (Bohr Model)
2n²
Where n = shell number (1, 2, 3...)
Charge Balance
Protons = Electrons (neutral atom)

🔬 Real-World Applications

  • 1.Chemistry: Understanding chemical bonding and reactions
  • 2.Materials Science: Designing new materials with specific properties
  • 3.Nuclear Energy: Understanding fission and fusion
  • 4.Medicine: Medical imaging (MRI, PET scans) and radiation therapy
  • 5.Electronics: Semiconductor design and quantum computing
