Definitions:

Atom Model

A representation or theory that describes the structure and behavior of atoms, the basic unit of matter. The most widely known example is the Bohr model, with electrons orbiting a nucleus.

Electrons

Electrons are subatomic particles with a negative electric charge, found in all atoms, and play a crucial role in chemical reactions and electricity.

Orbital Paths

Paths in space along which objects such as planets, moons, and satellites travel around another body.

Electron Shells

Electron shells are layers of electrons that surround the nucleus of an atom, where each shell has a different energy level.
