2010 Science News of the Year: Matter & Energy
Approaching the island of stability Smashing together the elements calcium-48, with 20 protons, and berkelium-249, with 97, has produced superheavy atoms containing 117 protons, albeit for a tiny sliver of a second (SN: 4/24/10, p. 15). Temporarily known as ununseptium, the new element fills an empty spot in the periodic table between the previously discovered […]
