When one pair of electrons is shared a single bond is formed. When two pairs are shared a double bond is created. A triple bond is made when three pairs are shared. Practice drawing the Lewis Structures of the examples given in the text on pages 42 - 44. Show this with a Lewis Structure.
Radiation is Energy.
The Sun produces an enormous amount of radiation, some of it high in energy, some of it low in energy. Light is one form of radiation. Radio waves, X-rays, color, and heat are all expressions of radiation. The wavelength is the distance between sucessive peaks and frequency is the number of wave passing a given point in a fixed amount of time. Wavelength and frequency are inversely related.
