For the elements with atomic number superior to 103 has stayed
proposed a standard method of attribution of the name, fully
grown from corresponding prefixes to each figure of the atomic
number, which addition comes an ending (106 = Un-nil-hex-io
= Une). 104 = Unnilquadio (Unq) realized in Urss in the 1964
and in Usa in the 1969, the two groups have respectively proposed
the names kurciatovio (Ku), and rutherfordio
(Rf). 105 = Unnilpenzio (Unp) realized in the 1970, and having
proposed the name hahanio (Ha). 106 = Unnilhexio (Une) realized in the 1974. 107 = Unnilseptio (Uns) realized in the 1975. 109 = Unnilennio (Unn) realized in the 1982. 110 = Ununnilio (Uun) realized in the 1994.
