Week of 2/29- 3/4 ENERGY IN CHEMISTRY Energy is the ability to do work. It is neither created nor destroyed, simply transferred. Kinetic energy and potential energy are present in chemical bonds SOURCES OF KINETIC ENERGY IN CHEMICAL SYSTEM -particles move and rotate through space -bonds vibrate -electrons move around nucleus SOURCES OF POTENTIAL ENERGY IN CHEMICAL SYSTEM -bonded atoms attract and repel -the attraction between nucleus and electrons, also the repulsion between electrons and electrons - Attraction b/w nucleus and shared electrons During chemical reactions, change occurs in BONDING - Changes in the way atoms are bonded involve changes in chemical potential energy - System- the reaction itself - Surroundings- imme
