Document Summary
Chem 1110: principles of chemistry 1 chapter 6 reading notes. Electronic structure the number of electrons in the atom and their distribution around the nucleus and their energies. Electromagnetic radiation: moves through a vacuum at 2. 998*10^8 m/s (speed of light, wavelength: distance between two adjacent peaks, frequency: number of complete wavelengths that pass a point each second. Frequency is in hertz (hz) or s^-1. Max planck proposed that energy is released/absorbed by atoms in chunks (quantum: planck"s constant: 6. 626*10^-34, matter can only be emitted/absorbed in whole number multiples of have. The intensity (brightness) of light is related to the number of photons striking the surface per unit time but not to the energy of the photon. Rydberg equation calculates the wavelengths of all the spectral lines of hydrogen. Electron is in ground state in n=1; excited state in n=2 and beyond. When delta e is positive, a photon must be absorbed as the electron jumps to a higher energy level.
