How does bond structure affect melting point? by

How does bond structure affect melting point? What is melting point? Melting point is defined as the temperature at which a solid object will transition to the liquid phase. In order for this to happen, energy (in the form of heat) is needed to break the bonds that hold a solid together. This means that an element with STRONGER BONDS has a
