Various polarization mechanisms involved in ionic crystals
WebIonic Bond Vs Covalent Bond. The ionic bond is the attraction between positive and negative ions in a crystal and compounds held together by ionic bonds are called ionic compounds. The covalent bond is a bond formed when two atoms share one or more electron pairs. Each atom contributes an equal number of electrons towards the bond formation. WebPolarising powers refers to the tendency of a cation to deform an anion, and this property is known as polarisation. Polarising power is directly proportional to charge density (charge to radius ratio). The cations having higher charge and lower size will have the highest polarising power. Al + 3 (Aluminium cation) has a high charge and smaller ... georgetown ghost walk
