WebJan 23, 2024 · Melting points determine whether the substance is a fat (a solid at room temperature) or an oil (a liquid at room temperature). Fats normally contain saturated chains. These allow more effective van der Waals dispersion forces between the molecules: more energy is required to separate the chains, increasing the melting point. WebBoth the melting and boiling points decrease down the group because of the decreasing strength of each metallic bond. The atoms in a metal are held together by the attraction of the nuclei to electrons which are delocalized over the whole metal mass. Tin, Sn, and lead, Pb, are both in group 14. Both are metals.
