At room temperature lithium is a soft metal that is silvery-white in color. These metals are usually dropped in water. Like most of the other alkali metals, you won’t find it in its pure elemental form in nature. For the average person, a periodic table is something that brings back memories of high school science classes, but it can be a treasure trove of information. What uses have been found for the remaining three alkali metals? Each alkali metal atom has a single electron in its outermost shell. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white. The alkaline earth metals are the elements that correspond to group 2 of the modern periodic table.
