1.	What were the weaknesses or limitations of Bohr’s model of atoms? Briefly describe the quantum mechanical model of atom?
Answer» r MODEL considers electrons to have both a known radius and orbit, which is impossible according to Heisenberg. The Bohr Model is very limited in terms of size. Poor SPECTRAL PREDICTIONS are obtained when LARGER atoms are in question. It cannot predict the relative INTENSITIES of spectral lines.
