How was seaborgium was made?

Answer 1

All the heavy synthetic elements are made in the same way, by using a particle accelerator to bombard some heavy element with heavy particles. The specific target element, and the specific particles with which it is bombarded, depend upon what you are trying to synthesize.

Answer 2

Seaborgium was obtained for the first time, simultaneously, by Albert Ghiorso, J.M. Nitschke, J.R. Alonso, C.T. Alonso, M. Nurmia, E. Kenneth Hulet, R.W. Lougheed, Glenn T. Seaborg from Berkeley, USA and by a team from Dubna, Russia - in 1974.

The nuclear reaction used was: 249Cf + 18O---------263Sg

Answer 3

By a particle accelerator, which speeds atoms up reeeaaaallly fast, which makes them more massive according to E=mc^2.
