Did you know?
Niels Bohr's model of the atom was the first to suggest that electrons moved in distinct orbits around the nucleus. Bohr's model also suggested that electrons could not exist between the orbits and that the energy of an electron depended upon its orbit. The model contained a lot of incorrect assumptions, such as the idea that electrons moved in perfect circles and that they could not have any other form of energy.

Bohr's Model of the Atom
A Danish scientist named Niels Bohr proposed a model of the atom in 1913. Bohr's model consists of a small, positively-charged nucleus surrounded by electrons that move in circular orbits. The model explains the chemical properties of atoms and is the foundation for modern atomic theory.
