In the structure drawn, all of the particles (yellow) are the same. In this particular case, the lattice points defining the unit cell coincide with the centers of the crystal's particles. This need not always be the case. The Ionic Lattice If a crystal is formed of ions, the compound ...

A related separation technique is sieving. Sieving refers to use of a single mesh or perforated layer to retain large particles while allowing the passage of smaller ones. In contrast, during filtration, the filter is a lattice or has multiple layers. Fluids follow channels in the medium to...

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...
