1What Did Einstein Say About Light? It is both a wave and a particle.
2Louis de Broglie, (France, 1892-1987) Wave Properties of Matter (1923) -Since light waves have a particle behavior (as shown by Einstein in the Photoelectric Effect), then particles could have a wave behavior.-He suggested electrons could be considered waves confined to a space around an atomic nucleus
7Erwin Schrodinger, 1925 Quantum (wave) Mechanical Model of the Atom -Developed equation (wave equation)that treated electrons in atoms as waves.-Only waves of specific energies providedsolutions to his equation.-Along with Heisenberg principle, this waveequation laid the foundation for modernquantum theory

9What Schrodinger’s Equation Means to Chemists Electrons do not travel around the nucleus in neat orbits.We only have a probability of finding an electron at a givenplace around the nucleus.-Electrons exist in orbitals that have three dimensional shapes.These orbital shapes are described by the solutions toSchrodinger’s wave equation for different energies.-Property of orbitals can be described by 4 quantum numbers.
10Four Quantum Numbers -Principal Quantum Number (n) -Orbital Quantum Number (l)-Magnetic Quantum Number (m)-Spin Quantum Number
