Bohr Model کا حساب کیسے لگائیں
Bohr Model کیا ہے؟
Bohr model describes hydrogen atom with electrons in discrete energy levels. Though superseded by quantum mechanics, it provides intuitive understanding of atomic structure.

n = 2 (first excited state)
نتیجہ
r = 4 × Bohr radius ≈ 212 pm, E = -3.4 eV
Relative to n=∞
عام غلطیاں جن سے بچنا ہے
- ✕Treating electron orbits as literal paths (they're energy levels)
- ✕Applying Bohr model to multi-electron atoms
اکثر پوچھے جانے والے سوالات
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.
