Believe it or not, everything around us (and within us) actually consists of different elements. From Alan's Factory Outlet, this infographic analyzes the average price of elements and what they're used for. Based on the data, it was found that the most expensive element out there is Polonium, which costs an astronomical $49.2 trillion per kilogram. Polonium is used for spacecraft, satellites, atomic weapons, and reducing static electricity in machinery.
Another very expensive element would be the second priciest, which is Actinium. At an average cost of $29 trillion, it's used for targeted alpha therapy, which is for cancer treatment. Of these 75 elements, the cheapest is Chlorine, which is used in many disinfectants and consumer products and is priced at an average of $0.08 per kilogram. Of the 75 elements shown on this infographic, 28 of them (37.33%) see an average price of more than $1,000.00 per kilogram.
