Chemical Bond
A chemical bond is a strong attraction between two or more atoms. Bond holds atom in molecule and crystal together (General Chemistry Online 2010).
Energy Consideration
Energy plays a key role in chemical processes. In the chemical reaction, bond between atoms in the reactant must be broken and molecule pieces or atoms are reassembled into product by forming new bond. Energy evolves as bonds are made energy absorbs to break the bond (Encyclopaedia Britannica 2014).
Chemical Reaction
Chemical reaction is a process in which the substances, the reactants, are converted to different substances. Substances are either chemical compound or chemical element. The example of activities are incorporate chemical reaction are burning fuel, making glasses, smelting irons, brewing beers etc.
