Silver sulfide is composed of silver, a metal, and sulfur, a non-metal; therefore, it is an ionic compound and a salt.
Generally not, since plated gold is generally clean gold on a base metal, while gold filled is from 5% and higher
No. Gold plate is a layer over a base metal. Gold is a combination of gold and another metal.
Silver is neither an acid nor a base. It is a metal.
A 14K gold plated jewelry means, 14 parts of gold to 10 parts alloy has been plated to a base metal. Gold plate is inexpensive but it gets more costly as the Karats are increased.
It would depend upon the base metal underneath the plating. If it's copper or brass for instance then probably not. If it's a tin based alloy of some sort, maybe.
First of all, theres no such thing as "silver plated sterling". Sterling is 92.5% silver, anything plated is just plated. If the item is solid sterling silver, its metal value depends on the current price of silver - but it may be worth more as a collectible. If it's plated base metal it has very little value.
Most circle earrings are completely sterling silver or sterling silver plated with gold. But some are a base metal, which depends on company, and then plated with gold. Most generally the plated base metal earrings are costume and not very valuable.
Depending on who makes them and their quality, they are made from either silver, nickel, or nickel-plated base metal.
EPS=Electro-Plated-Silver, also the stamp EPNS=Electro-Plated-Nickel-Silver. This is a base metal unfortunately, beneath a silvery skin.
It means you have a piece of silverplate that has 12 pennyweight of silver plated onto a base metal.

EPNS stands for "Electro Plated Nickel Silver". Nickel Silver (sometimes stainless steel) is the base metal onto which silver is plated. Despite its name, nickel silver contains no silver at all, but is an alloy of nickel, zinc & copper. A layer of pure silver is deposited electrolytically on the base metal to give a silver finish.
No genuine US silver dollars were ever made of plated base metal. Copies and fantasy pieces are often made that way, but real US dollar coins are made of the following metals:Up to 1935 : These are true silver dollars made of 90% silver and 10% copper1971-81 and 1999 : Not silver, but 75% copper and 25% nickel outer layers, bonded to a pure copper core2000-present : "golden" dollars made of manganese brass.
plated ie, its a base metal with a precious metal coating
I think you mean RWS EPNS-A1...RWS is just the manufacturer.EPNS stands for "Electro Plated Nickel Silver". Nickel Silver (sometimes stainless steel) is the base metal onto which silver is plated. Despite its name, nickel silver contains no silver at all, but is an alloy of nickel, zinc & copper. A layer of pure silver is deposited electrolytically on the base metal to give a silver finish.A1 is just the thickness of the silver plating. It usually varies between 30 - 35 Microns. It's one of the Highest Grades of Silver plating.
No - it does not mean gold over silver at all. It means "gold-shelled" which is another way of indicating that it merely gold plated. The base metal is rarely silver (or the plating would probably be called vermeil and not be hallmarked GS) and is probably just inexpensive base metal(s).
