Topic explanation

Standard explanation

The Bohr model describes the hydrogen atom using discrete allowed electron energy levels rather than a continuous range of energies.

Key points

• mvr = nħ
• Eₙ = −13.6eV/n²
• E₁=−13.6eV
• E→0
• Quantized Angular Momentum: Bohr proposed that an electron in hydrogen can occupy certain stationary states. In the historical
• Energy Levels of Hydrogen: The allowed energy levels are: Eₙ = −13.6eV/n² For: `n=1` E₁=−13.6eV This is the ground
• Atomic energies are discrete rather than continuous.
