The term 'Bohr Study' refers to the work of Danish physicist Niels Bohr, who is best known for his contributions to the understanding of atomic structure. He proposed that ATOMS are composed of a nucleus surrounded by electrons in orbits around the nucleus. His model of the ATOM was revolutionary and helped to explain the behavior of ATOMS in chemical reactions. Additionally, he proposed that the electrons in an ATOM can only occupy certain energy levels, which is known as the Bohr Model. This model is still used today in the study of atomic structure and chemistry.
