Ans:  Polar molecules have 2 parts with opposite charges - positive and negative, nonpolar molecules have no dipole, meaning that there is molecular symmetry, which results in no opposing charges.

A molecule is classified as a polar molecule when the arrangement of the atoms is such that one end of the molecule has a positive electrical charge and the other end has a negative charge. A polar molecule forms when an atom of high electronegativity bonds with a less electronegative atom.

Non-polar molecule does not have electrical poles. The electrons are distributed more equally. Therefore, a non-polar molecule does not have a profusion of charges at the opposite ends.

Ans: Chip Capacitor (tantalum chip capacitors): More than 90% of all tantalum electrolytic capacitors are manufactured in SMD style. It has contact surfaces on the end faces of the case and is manufactured in different sizes, typically following the EIA-535-BAAC standard.

Aluminum Electrolytic Capacitoris polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) (-) of the capacitor. A second aluminum foil called “cathode foil” contacts the electrolyte and serves as the electrical connection to the negative terminal of the capacitor.
