A shifting electron will always move from a more excited to a less excited state.
Scientists determined that electrons do not orbit the nucleus like planets. Instead, electrons can be anywhere in a cloud like region around the nucleus
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.

Niels Bohr introduced the notion of electronic orbits.
In Bohr's model, electrons in an oxygen atom occupy specific quantized energy levels called shells. Oxygen has two electrons in its innermost shell (K shell) and six electrons in its second shell (L shell). These electrons are arranged in a way that follows the principle of filling the lowest energy levels first before moving to higher ones.
From your question, In Bohr's model of the atom is energy give off or absorbed when electrons give offlight. From the word "off" i think the answer is too obvious, it gives off energy. And that is photon. The particle given off because of excess of electrons. Just get my point.

It added on Niels Bohrs model and his research. And anika's cool :D
