Chapter 5 Ionic and Covalent Compounds Unlike a mixture a compound cannot be separated into simpler substances by a physical process Valence electrons interact to make compounds Ionic compound consists of cations and anions Typically metal cations and nonmetal anions Held together by ionic bonding ( electrostatic attraction between oppositely charged particles) Lattice is 3d array of cations and anions Formation of an ionic compound gives off energy Lattice energy is the amount of energy required to convert a mole of ionic solid to its constituent ions in

Unformatted text preview: the gas phase Depends on magnitudes of charges and the distance between them . Atomic radii and coulomb's law can be used to interpret lattice energies Compounds with shortest distances between them have stronger attractions and therefore large lattice energy Law of definite proportions = different samples of a given compound always contain the same elements in the same mass ratio...
