Tennessine is the most recently discovered element, first created in 2010 by shooting calcium at another synthetic element – berkelium, with atomic number 97.
And that is precisely what Dr Dullmann intends to do in the case of element 119, by firing titanium atoms (number 22) at those of berkelium (97) and hoping some of them merge.
They started by creating an isotope of the element berkelium -- that alone took a year and a half -- and then bombarded it with isotopes of calcium, until … blammo.
