Did you know?
WebMelting and boiling points rise across the three metals because of the increasing strength of the metallic bonds. The number of electrons which each atom can contribute to the delocalised "sea of electrons" increases. The atoms also get smaller and have more protons as you go from sodium to magnesium to aluminium. Web(i) describe the variation in electron configurations, atomic radii, melting points and boiling points, 1. Period 2 elements all have 2 outer shells, whereas period 3 elements all have 3 outer shells. 2. Period 3 had an extra electron shell than period 2, …
WebExercise 3.3.1. Wikipedia pages for these substances can be found through these links, for phenol, benzene, benzaldehyde and benzoic acid. By thinking about noncovalent intermolecular interactions, we can also predict relative melting points. All of the same principles apply: stronger intermolecular interactions result in a higher melting point.
