Electron behavior refers to how electrons, which are negatively charged subatomic particles, interact with their environment and other particles. They are found in the outer regions of atoms, forming electron clouds around the nucleus, which contains protons and neutrons. Electrons can occupy different energy levels or orbitals, and their arrangement influences the chemical properties of elements, such as those in the Periodic Table. Electrons exhibit both particle-like and wave-like properties, a concept known as wave-particle duality. This means they can behave like discrete particles in some experiments and like waves in others. Their behavior is also governed by the principles of quantum mechanics, which describe how they can exist in superpositions and be entangled with other particles, leading to phenomena such as quantum computing.
