alkaline earth metalAny of the six chemical elements in the second leftmost group of the periodic table (beryllium, magnesium, calcium, strontium, barium, and radium). Their name harks back to medieval alchemy. Their atoms have two electrons in the outermost shell, so they react readily, form numerous compounds, and are never found free in nature.

| The mystery element is an alkaline earth metal, or one of a group
of elements that is highly reactive in nature. But he argues that placing
helium with the alkaline earth metals results in a more regularly shaped
structure that can take two forms. But this alkaline earth metal is more commonly found in
compounds (two or more elements that are chemically combined). |
