Niels Bohr
The scientist who first proposed that electrons existed in only certain energy levels around the nucleus was Niels Bohr. His model of the atom, known as the Bohr model, introduced the concept of quantized energy levels and provided a framework for understanding the behavior of electrons in atoms.
An electron's path around the nucleus defines its energy level. The energy levels are quantized, meaning electrons can only exist at specific distances from the nucleus.
In energy shells around and outside the nucleus of an atom!!!!
electrons occupy sublevels in the order of increasing energy .
The electrons move in specific energy levels or shells around the nucleus of an atom. These energy levels are also known as electron shells or orbitals. The electrons occupy these regions around the nucleus based on their energy levels.
Niels Bohr proposed the model of the atom where electrons move around a central nucleus in fixed orbits. This model helped explain the stability of the atom and the discrete energy levels of electrons.

Electrons are not found in the nucleus of an atom. Instead, electrons orbit around the nucleus in specific energy levels.

Electrons
Electrons exist in orbitals around the nucleus of an atom. It takes energy to knock an electron from the orbital it is in to an orbital a greater distance from the nucleus. The electron gives off energy when it falls closer to the nucleus. A Danish Scientist named Niels Bohr figured it out.

Because they are the outer electrons in an atom and they orbit around the nucleus. But you should ask a scientist this question. NOT put it on ask.com. OR look it up on google.com. it is very likely that you will find something there.
Electrons travel in specific energy levels around the nucleus of an atom. These energy levels are known as electron shells, and electrons move within these shells in a kind of "cloud" around the nucleus.
Electrons are basically surrounding the nucleus (containing the protons and the neutrons), and are "swirling" around the nucleus, forming a cloud like shape around the nucleus.
