- Periodic Table of Elements - PubChem
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack) While much of what is in the periodic table is stable and unlikely to change, the IUPAC organization is responsible for deciding what needs to be changed

- Nobelium | No (Element) - PubChem
In 1957, a group of scientists working at the Nobel Institute of Physics in Stockhlom, Sweden, announced the discovery of a new element They produced this new element, which they named nobelium, by bombarding a target of curium-244 with ions of carbon-13 with a device called a cyclotron
