WebAmong three type of primary bonds covalent bond has high melting point and strongest bond. Which are the metals has covalent bond nature some more high compare to other metals, those metals has higher melting point. So iron has higher covalent nature of bond compare to other metals. So it has higher melting temperature. See less WebWhat 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 HIGHER MELTING POINT.
