1 Niels Bohr suggested that electrons in an atom were restricted to specific orbits around the atoms nucleus. 2  Bohr argued that an electron in a given orbit has a constant energy, thus he named these orbits energy level.
Bohr's model of the atom is important because it introduced the concept of the quantum in explaining atomic properties.However, Bohr's model ultimately needed revision becuase it failed to explain the natue of atoms more complicated than hydrogen.rwin Schrodinger developed the equation which is used today to understand atoms and molecules-the Schrodinger Equation (1926) Erwin Schrodinger took the ideas developed by de Broglie, Heisenberg and others and put them together in a single equation that is named after him.
