Oganesson is named after 83-year-old Russian physicist Yuri Oganessian, and according to Richard Van Noorden from Nature, this is only the second time a new element has been named for a living scientist. Please note that the elements do not show their natural relation towards each other as in the Periodic system. (1983), "Zinc production in medieval India". Shortly after the discovery of rubidium, Crookes found a new green line in a selenium sample; later that year, Lamy found the element to be metallic. Another way to look at heaviness is in terms of density, which is mass per unit volume. It is believed that lead smelting began at least 9,000 years ago, and the oldest known artifact of lead is a statuette found at the temple of, The earliest gold artifacts were discovered at the site of.
