1. According to the periodic law: in the periods from left to right decreases the atomic radius, electronegativity increases. In order to it increases the energy of the outer electron to the nucleus. It’ s true also say that formed favorable electronic configuration (as an inert gas) when the electron separated from from the atomic nuclei of alkali metal. 2. Compounds with strong molecular bonds need more energy to get further apart and boil. Energy is proportional to temperature. The higher the temperature the higher the energy. So, if it takes more energy to break the intermolecular forces, it also takes more temperature. Expand on this-bring in that weak molecular forces take less energy so less temperature. 3. Fe2(SO4)3
