The existence of element Flerovium (perviously known as Ununquadium) (element 114) was confirmed in January 2009 at Berkeley, US. It appears to behave as the first superheavy element that shows noble-gas-like properties - possibly due to relativistic effects.
• Its appearance is unknown.
• Its category is unknown (but is suspected to be a noble gas, like neon, argon, xenon etc.).
• Its phase properties (gas/liquid/solid) are unknown.
