In the mid-1960s most of the coins were 90% silver, now there is about 21% in coins. Though percentages can vary based on the coin.
Silver is used to make jewelry like necklaces, bracelets, rings, etc. It is used for this purpose because it is very malleable and due to it's softness, it can be shaped into various shapes and sizes. It does tarnish easily, but only when exposed to ozone, hydrogen sulfide, or air containing sulfur.
"Oh, it's those silver things in my mouth!" Yes, it's what you get when you go to the dentist. They usually place it on top of your tooth to restore it's shape, size, strength, and appearance.
With evidence we can say that silver has been used for at least 5,000 years. It was known since ancient times. It was first mined in Anatolia (modern day Turkey). The main silver production then moved Greece’s Laurium mines in 1200 B.C. Then around 100 A.D., Spain became the capital of silver production. Several major silver min discoveries happened between 750 and 1200 A.D, including the Germany and Eastern Europe. From 1000 and 1500 A.D., mines flourished and improvements in technology and production were made. From here on everything flourished and improved even more.
Silver's atomic number is 47. An element's atomic number tells how many protons are in it. It is also equal to the amount of electrons in an element. When looking on the periodic table, there are two numbers, it is usually the smaller number.
Silver's mass number is 108, it's the rounded number from the atomic mass. It's the total number of neutrons and protons in an element.
Protons, Neutrons, Electrons
There are 47 protons and electrons in Silver, this number is also the same as the atomic number. Silver has 60 neutrons, to find the amount of neutrons in an element, you take the mass number minus the atomic number.
