Can we crack the code to build the world of the future? By digging, these guys are hoping to strike it rich. I'm on a quest to understand the basic building blocks of everyday matter. These symbols represent the atoms that make up every single thing in our universe: 118 unique substances arranged on an amazing chart that reveals their hidden secrets to anyone who knows how to read it. It turns out that nature has concealed thousands of pounds of the stuff under billions of cubic feet of earth.Using cyanide to react with the gold allows them to gradually reduce 40,000-gallon tanks of pulverized sludge to this: three trays full of mud? This is the first time an outsider has been allowed to pour gold. I'm not sure they entirely know what they are doing, but they are going to let me pour the gold into a gold bar mold. They'll have to throw it away or just let me take it home in my luggage. Once he removes the aluminum and joins the two halves, a bell-shaped space remains on the inside, ready to accept the molten bronze. That's a, that's a mixture, actually, of 80 percent copper and 20 percent tin. A blow causes the atoms to vibrate, but the tin prevents them from moving too far out of position.Tin is good for a bell, but only in the right proportion.Muller's lab has successfully captured many other images of atoms in gold and computer chips, oxygen, powerful magnets and even glass.
They're the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. The good news is that we haven't finished; there may be still gold hiding in the mix. And, today, it's one of the most widely bought and sold metals in the world. Copper is in wire, electronics and computer chips, plumbing and other building materials. These guys can trade their copper futures; I've got to unload my copper today. In pure metals, the atoms are arranged in orderly rows and columns.
Here, at the Cortez Mine, in Nevada, high-tech prospectors are moving mountains, closing in from above and below. Which raises a question: if the gold is invisible to the naked eye, how do they even know if they're digging in the right place? Eight bars, million, sitting on this unassuming little table. Of all the elements that touch our lives, nothing drives humankind to acts of love or destruction like gold. Copper alone is impressive stuff, but when ancient metallurgists combined it with another element, they invented a much tougher material that went on to conquer the world. Tin; symbol Sn; atomic number 50—50 protons and 50 electrons.
If you're like me, you care about the elements and how they go together,… The problem is it's exceedingly rare stuff in the earth's crust, and it's getting harder to find all the time. Mike tells me that each bar represents about a million pounds of rock that had to be moved and processed.
About three quarters of the elements are metals, and gold is one of the most standoffish. In copper, they can slide past each other easily, which makes it relatively soft and easy to dent, not right for a bell. Ralph places the form into a circular steel sleeve, then fills the space around it with a mixture of sand and epoxy, to withstand the searing heat of the hot metal. Adding tin to copper during melting changes the properties of the metal.
How an atom reacts chemically depends on how willing it is to share electrons with others, and gold is not very social. So do other so-called "noble" metals: silver, platinum, palladium, osmium and iridium, all located in the same quiet neighborhood of the periodic table. The golden mud goes into a 2,000-degree induction furnace, along with a white powder called flux, chemicals that prevent the molten gold from reacting with or sticking to anything. When this company started, they used a mixture of horsehair, manure and just about anything else that would hold a shape without burning, but the goal was the same: to create a hollow shape that follows the inner and outer perimeter of the bell. The larger tin atoms restrict the movement of the copper atoms, making the material harder.
