Question

Define the termsa)polarizability b)dipolemoment​

Answer 1

Answer:

a)Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. ... Polarizability is responsible for a material's dielectric constant and, at high (optical) frequencies, its refractive index.

b)Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment.
