Scientists concluded that electrons occupy specific energy levels by exciting atoms of different elements with UV light and watching the light emitted as the electrons fall back to ground state. Different elements had different characteristic emissions each time.
Electrons are not found in the nucleus of an atom. Instead, electrons orbit around the nucleus in specific energy levels.
Electrons move around the nucleus of an atom. Protons and neutrons are located in the nucleus at the center of the atom. Electrons orbit the nucleus in specific energy levels, or shells.
In this model, the electrons move or orbit around the protons that are at the center of the atom. Electrons move around the nucleus, which contains the proton, in orbits that have a definite size and energy.
Electrons are the particles found in shells around a nucleus. They are negatively charged and move in orbitals at specific energy levels.

Niels Bohr proposed the idea that electrons orbit around the nucleus in specific energy levels. This model, known as the Bohr model, was a significant advancement in understanding the structure of the atom.

The particles found in the area surrounding the nucleus are called electrons. Electrons are attracted to the protons in the nucleus, but are repelled from other electrons. This is why they can be found orbiting the nucleus.

Electrons are the only subatomic particles that are not found in the nucleus of an atom. They orbit around the nucleus in specific energy levels.
