Electron Configuration:This describes how electrons are distributed among various atomic orbitals in an atom, similar to how tenants might be distributed across different floors in our apartment building analogy.
Quantum Numbers: These numbers describe properties of atomic orbitals and their electron occupants, much like tenant records might detail who lives where in our apartment building.
Valence Electrons:These are electrons that occupy the outermost shell or highest energy level of an atom – they're like the tenants who live on the top floor of our apartment building.
