The book also includes an afterword by the author, and a foreword by Theodore Gray who was awarded the IgNobel Prize for Chemistry in 2002. The Periodic Table of Science

It is unknown how far the periodic table might extend beyond the known 118 elements, as heavier elements are predicted to be increasingly unstable. Glenn T.

There is currently no consensus on the placement of elements beyond atomic number 120 in the periodic
