Nobelium (No) - Element 102 on the Periodic Table #189853 (License: Personal Use)

Nobelium is a synthetic, highly radioactive metal in the actinide series, with no stable isotopes; its most stable isotope, No-259, has a half-life of about 58 minutes. It was first identified by a team at the Nobel Institute of Physics in Sweden and later confirmed by researchers in the USSR and USA. Due to its scarcity and short half-life, nobelium has no practical applications outside fundamental nuclear research.
