when an element is heated to its melting point the mettalic bond that bounds the atoms together breaks thats why metal turns to liquid.

The chemical reaction that takes place when an element is heated to its melting point is Decomposition. Most of the elements undergo decomposition through heating ( The triangle in the chemical equation) and Heating is known mostly to give a by product of 02 (oxygen with subscript 2), a process similar to oxidation.

When an element is being heated to its melting point - it is changing from a solid to a liquid. The particles in the element become hotter and hotter as more heat energy passes through. This is because the thermal energy is giving them kinetic energy and so they move faster and knock into each other more. As a result of the particles knocking into each other more - they create more heat and they also move further apart. Eventually - some of the bonds between the particles break from the fixed solid formation and so some of the particles can move more freely which is when it turns to a liquid.
Hope I've helped. x

There is not necessarily any chemical reaction when an element is heated to its melting point, since melting is a physical change. If there is any reaction, it will be oxidation (making an oxide) by reaction with oxygen in the air at this temperature.
