Name:_______________________________________ Date:______________________________ Blk:____ The Quantum Mechanical Model of the Atom The quantum mechanical model of an atom is a mathematical description (called Schrodinger’s equation) of the regions in space around the nucleus in which an atom’s electrons will probably be found. This region of space is called an atomic orbital and the shape of an atomic orbital (that is the shape of the electron probability density) changes as energy changes. The shapes of the three lowest energy orbitals are shown below. Note that an orbital in the quantum mechanical sense is nothing like Bohr’s orbits. s-Orbital Try drawing p-Orbitals Try drawing d-Orbitals Try drawing
