According to Neils Bohr, where are electrons located?

The correct answer indicates that electrons are found in energy levels surrounding the nucleus. This understanding stems from Neils Bohr's atomic model, which introduced the concept of quantized energy levels for electrons. In Bohr's model, electrons occupy specific orbits or shells around the nucleus, each associated with a particular energy level.

Bohr proposed that electrons can only occupy these defined energy levels and can move between them by absorbing or emitting energy in the form of photons. This model marked a significant development in atomic theory, showing that electrons do not randomly scatter throughout the atom or reside solely within the nucleus. Instead, their positions are defined by these energy levels, which helps explain the stability of atoms and the absorption and emission spectra observed in elements. This framework provides a foundation for more advanced quantum mechanical models that further refine our understanding of electron behavior.
