Document Summary
The way in which electrons are arranged in atoms or molecules. The manner in which atoms or ions are bonded to each other in molecule or ionic networks. The specific distribution of these particles in three dimensional space. Connectivity: predict how atoms or ions are bonded to each other in the particles of a given substance. Spectroscopy: based on the analysis of different types of em radiation absorbed or emitted by chemical substances. Wavelength is a measure of the distance over which the shape of the wave is repeated. The frequency indicated the number of repeating waves that cross a certain point of space per unit of time. Not independent of each other and their relationship depend on the speed at which the waves travel through a certain medium. Wavelength, frequency (v), and speed of propagation of a wave are related to each other through: em waves traveling through vacuum= speed of propagation has the constance value.
