What are quantum numbers? ⚛️
Quantum numbers are values that describe the position, energy, shape, and orientation of an electron inside an atom. They help explain how electrons are arranged in orbitals around the nucleus. The principal quantum number shows the energy level, the azimuthal quantum number shows the orbital shape, the magnetic quantum number shows orbital orientation, and the spin quantum number shows electron spin direction. Together, they help predict atomic structure and chemical behavior.
