Як розрахувати Bohr Model
Що таке 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 Though superseded by quantum mechanics, it provides intuitive understanding of atomic structure.

Часті запитання
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.
