         Ghiorso should also be credited with element 110  | 
      
         Al Ghiorso tells an engrossing story  | 
         The HILAC was used to synthesize 102  | 
         Actually, 99 (einsteium) and 100 (fermium)  | 
| 
         For elements beyond 100  | 
         A hypothesis of the nuclear physicist  | 
         A special dream of Ghiorso  | 
         Fermium (atomic number 100)  | 
         Ghiorso was still engaged in research  |
