![]() Metals are good conductors of both heat and electricity because they contain delocalised electrons which are free to move around. Metals can conduct electricity and heat.This is because there is a greater electrostatic attraction between the positive ions and delocalised electrons and hence the metallic bond is stronger and requires more energy to break. As the number of delocalised electrons per metal atom increases, the melting point increases. The more delocalised electrons present, the higher the melting point of the metal.This strong electrostatic force of attraction is difficult to overcome and a large amount of energy is needed to break it, therefore a high temperature is required. The melting and boiling points of metallic compounds is usually quite high because the positive metal ions are strongly attracted to the delocalised electrons. Metals have high melting and boiling points. ![]() The arrangement of ions and electrons in the compound determines whether or not the compound can conduct electricity as well as the melting and boiling point of the compound. ![]()
