CH 301 Lecture Notes - Lecture 11: Lewis Structure, Lattice Energy, Ionic Compound
Document Summary
Ionic bonds formed when electrons are completely transferred between atoms giving oppositely charged ions cations and anions. The outermost shell is comprised of an s orbital and three p orbitals. The maximum number of electrons in the valence shell is eight. Atoms tend to gain or lose electrons in order to attain an electron configuration resembling a noble gas. Forms lattice of anions and cations held together by a strong electrostatic attraction. Lewis dot structures: shows the number of valence electrons the element has to lose or gain in a chemical reaction to form a bond. Coulomb"s law: for two charges interacting the potential energy is directly proportional to the magnitude of the charges and inversely proportional to the distance between them. Lattice energy: energy required to completely separate one mole of an ionic solid into gaseous states. Lattice energy tracks with coulomb"s law but it is not equal to it.
