Bohr’s model, however, suggested that certain orbits were stable and would not radiate energy. Moreover, the model was able to explain the hydrogen atom’s spectral lines, a problem that had ...

For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model ...

Everyone at that time imagined the atom as a ... the electrons in his model lined up with the regular patterns (spectral series) of light emitted by real hydrogen atoms. Bohr's theory that ...

5. A hydrogen atom initially at the ground level absorbs a photon, which excites it to the n = 4 level. Determine the wavelength and frequency of the photon. 6. (a) Using Bohr’s model calculates ...

The 2025 Board exams are around the corner and it is time for the students to revise the syllabus and start practising the ...
