Briefly describe how ions are formed.
Ions form when atoms gain or lose electrons, resulting in a net electric charge. Losing electrons forms cations (positive ions), while gaining electrons forms anions (negative ions).
Describe how electrons transition between energy levels in the Bohr model.
Electrons can jump from one energy level to another by absorbing or emitting photons with energy equal to the energy difference between the levels.
What is the key difference between Carbon-12 and Carbon-14?
Carbon-12: 6 neutrons | Carbon-14: 8 neutrons (different number of neutrons)
Compare and contrast Cations vs. Anions.
Cations: Positive charge, fewer electrons than protons | Anions: Negative charge, more electrons than protons
Compare the Bohr model with modern quantum mechanics.
Bohr Model: Simplified, electrons in fixed orbits | Modern Quantum Mechanics: Orbitals, probability functions, more accurate for complex atoms
