Lattice Energy Energy change when gaseous ions form an ionic solid, indicating bond strength and affecting physical properties. Exothermic Reaction A process where energy is released, often resulting in a negative change in enthalpy. Endothermic Reaction A process where energy is absorbed, often resulting in a positive change in enthalpy. Coulomb's Law A principle used to calculate the force between two charged particles, foundational for lattice energy calculations. Ionic Solid A compound formed by ions held together in a lattice structure, characterized by high melting and boiling points. Gaseous Ions Ions in the gas phase, often used as reactants in lattice energy calculations. Cation A positively charged ion, often a metal, that participates in forming ionic bonds. Anion A negatively charged ion, often a non-metal, that participates in forming ionic bonds. Radius The distance from the center of an ion to its outermost electron, affecting lattice energy. Boiling Point The temperature at which a substance transitions from liquid to gas, influenced by lattice energy. Melting Point The temperature at which a solid becomes a liquid, influenced by the strength of ionic bonds. Solubility The ability of a substance to dissolve, inversely related to lattice energy in ionic compounds. Lattice Dissociation Energy Energy required to break an ionic solid into gaseous ions, indicating bond strength. Periodic Table A tabular arrangement of elements, used to determine ionic radii for lattice energy calculations. Ionic Bond A chemical bond formed between oppositely charged ions, strength determined by lattice energy.
