Question
Which one of the following is not correct as per the limitations of Bohr’s model of atom?
- Failed to explain the dimension of the molecule.
- Failed to explain the stability of an atom.
- Could not explain the arrangement of electrons for heavier atoms
- Both A and C
Hint:
Bohr's theory didn't fail to explain the stability of an atom. So this can't be considered a limitation.
The correct answer is: Failed to explain the stability of an atom.
- Bohr's theory says that the electrons in the orbits have fixed energy.
- His theory mainly focused on atoms with smaller sizes and with fewer electrons.
- Bohr's theory mainly explained the stability of atoms
