Bohr's Atomic Model
Manocha Academy・2 minutes read
Niels Bohr's atomic model revolutionized atomic theory by addressing the stability of atoms and the observation of line spectra. Bohr proposed fixed circular orbits for electrons with quantized angular momentum, rectifying previous models' issues like Rutherford's inability to explain atom stability.
Insights
- Neils Bohr's atomic model revolutionized atomic theory by introducing fixed circular orbits for electrons, quantized angular momentum, and energy transitions between shells, addressing the stability of atoms and line spectra observations.
- The formula to calculate the radius of electron shells, V, kinetic energy, potential energy, and total energy provides a comprehensive understanding of electron behavior in Bohr's atomic model.
- The concept of quantized energy levels in Bohr's model explains the line spectrum phenomenon, where only specific energy values are accepted, leading to the emission of light of distinct colors and frequencies during electron transitions.
