Hello, my name is Gold. Most people call me by my nickname, which is Au. My nickname comes from the Latin word for gold, “aurum”. I have many uses and some of them you may have never heard of. Humans probably have known me and treasured me since prehistoric times. No one knows who really discovered me but humans do know that they can trace back their use of me back to at least 6300 years ago. My wide spread use over the course of human existence is the very reason that no one knows who discovered me. I belong to the group of elements called the transition metal group. I have several oxidation states and I also have a very high melting point which is around 1337.33 Kelvin. That is very high, in Fahrenheit it is 1947.92 degrees and in Celsius it is 1064.18 degrees. I am also paramagnetic, which means that I have very weak attractions to magnetic forces and can only be attracted when in the presence of an externally applied magnetic field.

I am usually found around the middle part of the periodic table. I am found below Silver and between the two elements, Platinum and Mercury. I am placed in the d-block element section of the periodic table. My atomic number is 79 and the mass of my most stable isotope and is basically my atomic mass is 196.967. The type of phase that I am at room temperature is solid. I am the most malleable and ductile of all metals. If you take one gram of me and start beating me repeatedly with a hammer of some sort, you will soon end up with a sheet of one square meter. If you take one ounce of me, you will end up with 300 square feet.

I have been used widely throughout the world as a thing for financial exchange. I get used like that either by issuance and identification of gold coins or other metal quantities. When I am in use of day-to-day economic or financial use, I typically get a little harder by mixing myself with other metals such as copper, silver, and other base metals. If I just use myself just as pure gold itself, than I...
