Bohr model describes hydrogen atom with electrons in discrete energy levels. Though superseded by quantum mechanics, it provides intuitive understanding of atomic structure.
단계별 가이드
- 1Enter principal quantum number (n)
- 2The calculator finds electron radius, energy, and transition frequencies
- 3Results show orbital properties
풀어진 예시
입력
n = 2 (first excited state)
결과
r = 4 × Bohr radius ≈ 212 pm, E = -3.4 eV
Relative to n=∞
피해야 할 일반적인 실수
- ✕Treating electron orbits as literal paths (they're energy levels)
- ✕Applying Bohr model to multi-electron atoms
자주 묻는 질문
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.
