The elements in column 1, known collectively as the alkali metals (except hydrogen), always lose their one valence electron to make a +1 ion.
All of the s-block elements are unified by the fact that their valence electrons (outermost electrons) are in an s orbital. The ionic forms of potassium, strontium and barium make appearances in firework displays as the brilliant purples, reds and greens. Elements in column 2 (the alkaline earth metals) always lose their valence electrons to form +2 ions.

In general, they are shiny, silvery, good conductors of heat and electricity and lose their valence electrons easily. S-block elements are famous for being ingredients in fireworks. Elements in column 1 have one electron in the s orbital, and elements in column 2 (plus helium) have two electrons in the s orbital. These metals react extremely vigorously with water and even oxygen to produce energy and flammable hydrogen gas. Helium is one of the noble gases, an especially nonreactive group of gases that reside on the far right side of the periodic table.
