Lattice Energy Trends In physical chemistry, the electrostatic potential energy of two interacting charged particles is calculated by the formula; {eq}E_{el} = \frac{k\;Q1\;Q2}{d} {/eq} where, Q1 and Q2 are the charges on the ions in Coulombs, with their signs; d is the distance...
Definition of Phonons What is a Phonon? The phonon is a vibration of theatomic lattice. In normal circumstances, atoms vibrate as a result of their thermal energy. The higher the thermal energy, the greater the vibrational energy. In a solid lattice, independent vibration of one atom is not...
