The two dots are the atoms two 4s valence. Atomic Orbitals Solutions to the Schrodinger equation give the energies, or energy levels, an electron can have The Schrodinger equation leads to a mathematical expression called an atomic orbital An atomic orbital is a mathematical representation that describes the probability of finding an electron at various locations around the nucleus; which is represented as a region where there is a high probability of finding an electron. 5 MHz, what is the wavelength of the stations. Light travels slower in water than it does in air; however, its frequency remains the same. Limitations to Rutherford's ATOMIC MODEL Rutherford's model could not explain the chemical behavior of elements Example: why metals or compounds of metals give off characteristic colors when heated The explanation of what leads to the chemical properties of elements required a model that would show the behavior of electrons in atoms.
