	Given the phenomenon of polarization, we can then define polarizability as the ease with which the charges in an object can be separated. It measures the tendency of matter to acquire an electric dipole when it is affected by an electric field. Polarizability is a constant value, represented by the Greek character alpha, that is inherent and unique to each material and is commonly determined experimentally. It is measured in units of volume such as cubic meters. Polarizability influences a material's ability to store electrical energy when subjected to an electric field, which is important in dielectric materials used in capacitors and insulators. Molecules with more loosely held electrons or that have larger electron clouds tend to have higher polarizabilities.

			Polarizability affects the strength of van der Waals forces and London dispersion forces between molecules, which influence properties such as boiling points, melting points, and solubility. Polarizability also determines how a material interacts with light, affecting the ability to scatter or absorb light.

			Insulators:
	An insulator is a material through which mobile charges cannot flow, and a conductor is a material through which mobile charges can flow.		An insulator is a material through which mobile charges cannot flow, and a conductor is a material through which mobile charges can flow.

	In an insulator, the separation of charge simply causes the electrons of the object being polarized to position themselves on the outer surfaces of the object.		In an insulator, the separation of charge simply causes the electrons of the object being polarized to position themselves on the outer surfaces of the object.
			It contributes to the material's dielectric properties, affecting its ability to store electrical energy when it comes into contact with an electric field.
			Polarization can lead to the formation of surface charges at the interfaces between the insulator and its surroundings, which can influence the material's behavior in various applications.
			In ferroelectric materials, polarization can be permanent and exhibit hysteresis behavior, meaning that the material retains its polarization even when the external electric field is removed.

			Conductors:
	On the ~~other hand,~~ in conductors, the electron field induces a flow within the conductor of electrons from the heavily negatively charged side of the object to the heavily positively charged side of the object.		Conductors are materials characterized by their high electrical conductivity, meaning that they have free electrons that can move easily through the material in response to an applied electric field.
			In conductors, the electron field induces a flow within the conductor of electrons from the heavily negatively charged side of the object to the heavily positively charged side of the object. When a conductor comes into contact with an external electric field, the free electrons redistribute themselves almost instantaneously to cancel out the electric field within the conductor. This redistribution of charges leads to an equilibrium state where the net electric field inside the conductor is zero.

	Polarization is defined theoretically [http://www.physicsclassroom.com/class/estatics/Lesson-1/Polarization defined] as "the process of separating opposite charges within an object" by the application of an external electric field.		Polarization is defined theoretically [http://www.physicsclassroom.com/class/estatics/Lesson-1/Polarization defined] as "the process of separating opposite charges within an object" by the application of an external electric field. Polarization is the separation of the center of positive charge and the center of negative charge in a material.

	Essentially, exposure of an atom to an external electric field causes the electron cloud of an atom to surround the positively charged nucleus of the atom opposite the direction of the electric field, causing one side of the atom to be positively charged and one side to be negatively charged.

	~~When~~ the positive and negative charges within an object have become separated, the object is said to be polarized.		As you know, negative and positive will always repel each other. So when the positive and negative charges within an object have become separated, the object is said to be polarized.

	Due to the physical separation of its positive and negative charges, a polarized object can behave like a dipole, so long as the charges remain separated. Once the electric field causing the polarization is removed and the positive and negative charges are no longer separated, the dipole disappears.
