Systematic element name

temporary name assigned to newly synthesized or not yet synthesized chemical elements

Systematic names are given by IUPAC to discovered elements like element 106 and beyond. The parts of the names are nil=0, un=1, bi=2, tri=3, quad=4, pent=5, hex=6, sept=7, oct=8, and enn=9. The last part of the name is ium. Element 110's older name was ununnilium (un-un-nil-ium), which means 110, and the same for element 118, ununoctium (un-un-oct-ium), which means 118.
