The temporary name of element-107 is unnilseptium (pronounced oon-nil-SEPT-i-em) with a symbol of "Uns".

In 1976, the Soviets reported they had produced an isotope of element-107. Since then, their claim has been substantiated by German researchers. There hasn't been a proposed name suggested for element-107.
