Как да изчислим Bohr Model
Какво е 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 Though superseded by quantum mechanics, it provides intuitive understanding of atomic structure.

Worked Examples
Вход
n = 2 (first excited state)
Резултат
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.
