The ions formed have a full outer electron shell, so are very stable. See the study guide on groups in the periodic table for more information.

Currently, there are 118 known elements on the periodic table, from hydrogen all the way ... 244 with additional neutrons and vaporized ions of titanium. They think the same strategy could be ...

Particle-accelerator study focuses on the r-process thought to be responsible for forming elements heavier than iron ...

In the 1980s and 1990s, Roberto noted, scientists at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, ran “cold fusion” experiments that extended the periodic table from ...

That’s why this periodic table clock really caught our eye. [gocivici]’s idea is a simple one: light up three different elements with three different colors for hours, minutes, and seconds ...
