What does the element gold represent?

Gold is element 79 and its symbol is Au. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek. It’s abundance in the earth’s crust is 0.004 ppm. 100% of gold found naturally is isotope Au-197.

But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.

Is gold a rock?

Gold is a valuable, yellow metal. Gold is usually found in metamorphic rock. It is found in underground veins of rock where the inside of the Earth heats the water that flows through the rock.

What hardness is gold?

For comparison, pure gold is 2.5, on the MOHs scale. That’s about the same hardness as your fingernail. That will not work for jewelry making. When white gold is prepared for jewelry making, by adding alloy metals, for example at 14kt or 58% pure gold, its hardness gets bumped up to 3.5 – 4.

Can gold be made?

Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. Gold is the chemical element with 79 protons in each atomic nucleus.

Is gold natural to earth?

In its natural form, it is found deep in the layers of the earth where it is transported by water, molten lava and volcanic eruptions, and earthquakes. Geologists have found gold in rocks as old as 4.5 billion years ago.

Is gold toxic to humans?

Gold is toxic if consumed regularly. The symptoms of gold poisoning are no different than other forms of metal poisoning. The primary difference between gold and uranium is that gold isn’t very reactive and so it has virtually no contact toxicity.

What is special about gold?

Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the most malleable and ductile of the elements; an ounce (28 grams) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf.

How does gold form in nature?

All of the gold found on Earth came from the debris of dead stars. As the Earth formed, heavy elements such as iron and gold sank toward the planet’s core. It make occur as flakes, as the pure native element, and with silver in the natural alloy electrum. Erosion frees the gold from other minerals.

Who found the element gold?
