Etymology

Ununquadium was a temporary name scientists made from number parts: un- 'one', un- 'one' again, quad- 'four', and -ium 'metal'. So the name literally means 'one-one-four', the element's number, which is why older books used ununquadium before the element got the permanent name flerovium.
