WebThe melting point of a material is primarily related to bond strength. Materials with strong bonds between atoms will have a high melting temperature. However, other factors--such as crystal structure, atomic … WebHigh Melting and Boiling Points As a result of powerful metallic bonding, the attractive force between the metal atoms is quite strong. In order to overcome this force of attraction, a great deal of energy is required. This is the reason why metals tend to have high melting and boiling points. the classic illustration
