Document Summary

Is the displacement of an object against an opposing force. The attractive electrical force between opposite charges of electrons (-) and nuclei protons (+) holds atoms together. = are the charges of two ions and . : chemical energy or bond energy results when the electrons and nuclei arrange to minimize the electrical potential energy. Every compound (like salt) has stability that correlates with its chemical energy. When bonds combine they release energy hence stability increases. When bonds separate they absorb energy hence potential energy increases. The higher the temperature of a compound, the greater the thermal energy. Molecules that rotate are form of kinetic energy. Molecules that vibrate are a combination of kinetic and potential energy. The energy content of electromagnetic radiation. The interactions between radiations and matter helps chemicals to study the structure of compounds. Radiant energy = electromagnetic radiation , for example: sunlight, microwave radiation, radiowaves and many more.
