Missing heavy elements
From Mendeleyev's famous Table,
Chemists to find were intent.
In Japan, the quest was keen,
And after many years, indeed,
Element No. 113
To create they did succeed.
At high speed, bizmuth was subjected,
To an atom's beam of zinc,
And finally, as expected,
It produced the missing link.
Thus Dr. Morita will be able
To name the element, and it
Will finally the Table
And its bottom line complete.
