Ako vypočítať Bohr Model
Čo je Bohr Model?
Bohr model describes hydrogen atom with electrons in discrete energy levels. Though superseded by quantum mechanics, it provides intuitive understanding of atomic structure.
Sprievodca krok za krokom
- 1Enter principal quantum number (n)
- 2The calculator finds electron radius, energy, and transition frequencies
- 3Results show orbital properties
Worked Examples
Vstup
n = 2 (first excited state)
Výsledok
r = 4 × Bohr radius ≈ 212 pm, E = -3.4 eV
Relative to n=∞
Common Mistakes to Avoid
- ✕Treating electron orbits as literal paths (they're energy levels)
- ✕Applying Bohr model to multi-electron atoms
Frequently Asked Questions
Why can't electrons radiate away and fall to nucleus?
Bohr postulated discrete energy levels with no intermediate states; electrons jump between levels, emitting specific frequencies.
Why is Bohr model incomplete?
It only works for hydrogen; it can't explain multi-electron atoms or fine structure revealed by quantum mechanics.
