Tarnished silver is the same as oxidized silver.
Oxidized silver is not necessarily sterling silver but sterling silver can be oxidized. Oxidation is a finish on silver, otherwise known as tarnish. Sterling silver can tarnish and silver plate can tarnish, too.
Silver is a silver-white metal that does not tarnish easily due to its resistance to corrosion.
Pure silver can tarnish but not as easily as Sterling Silver.
The black tarnish on silver is silver sulfide, Ag2S. Presumably you are boiling silver in a metal pot. The salt water completes an electrochemical cell between the silver sulfide and the aluminum, copper, or iron pot. The oxidized silver in silver sulfide is reduced to silver metal, and part of the metal pot is oxidized; the reaction happens because silver wants to be reduced more than the other metals do. You might imagine that as the metal is oxidized it would become iron, copper, or aluminum sulfide, but the metal sulfides, especially aluminum sulfide, are not so stable. Aluminum sulfide hydrolyzes to aluminum hydroxides and hydrogen sulfide, H2S, the stinky gas, which is probably what you are calling "sulfur".
When a ring is oxidized, it means that the metal has reacted with oxygen in the air or with certain chemicals, leading to the formation of a layer of tarnish or discoloration on its surface. This tarnish can give the ring a dull or darkened appearance, which can be removed with cleaning and polishing.

Silver is a silver-white metal that does not tarnish easily due to its resistance to corrosion.
The word "tarnish" in the sentence "the silver will tarnish if it is not polished often" is a verb. It is describing the action of the silver in the sentence.

Silver. The purer the silver the more rapidly it will tarnish.

Yes.
It is a chemical change. Oxygen from the air combined chemically with the silver to form silver oxide- that is the tarnish.
