    Study Notes

    • Louis de Broglie proposed that matter in motion has wave-like characteristics, leading to the concept of matter waves
    • Davisson and Gerner, and G.P. Thomson conducted an experiment on electron diffraction, confirming electrons as waves
    • Erwin Schrodinger applied de Broglie's theory to the electron in an atom, creating the Schrodinger Wave Equation
    • Schrodinger's model describes the motion of an electron in an atom, resulting in atomic orbitals
    • Niels Bohr initially proposed the atomic model with electrons revolving around the nucleus
    • Energy levels are represented by numbers or letters, and are subdivided into sublevels
    • Sublevels consist of four types: s, p, d, f
    • Electrons are distributed among these energy levels, sublevels, and atomic orbitals in an atom
    • Quantum numbers describe the atomic orbital where an electron may be found
    • Principal quantum number (n) indicates the average distance of the electron from the nucleus
    • Azimuthal quantum number (l) indicates the subshell in which the electron moves
    • Magnetic quantum number (ml) indicates the orientation of the electron orbital
    • Spin quantum number (ms) indicates the spin of the electrons in the orbital.
