Ionic cohesive energy
Did you know?
WebThermal energy easily overcomes the cohesion and so these are gases at RT. Alkali metals (le ) have intermediate energies. In the middle of the periodic table the cohesive energies are typically strong. Physical properties such as melting temperature and bulk modulii vary roughly as the cohesive energies.
