• Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal The alkaline earth metals are six chemical elements in group 2 of the periodic table.They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.. Structurally, they (together with helium) have in common an outer s ...
  • Alkaline-earth metal | chemical element | Britannica

    www.britannica.com/science/alkaline-earth-metal The alkaline-earth metals were later produced by reduction of their salts with free alkali metals, and it was in this way (the action of potassium on beryllium chloride) that beryllium was first isolated by the German chemist Friedrich Wöhler and the French chemist Antoine Bussy independently in 1828.

    www.britannica.com/science/.../Physical-and-chemical-behaviour Alkaline-earth metal - Alkaline-earth metal - Physical and chemical behaviour: The alkaline-earth elements are highly metallic and are good conductors of electricity. They have a gray-white lustre when freshly cut but tarnish readily in air, particularly the heavier members of the group. Beryllium is sufficiently hard to scratch glass, but barium is only slightly harder than lead.

    courses.lumenlearning.com/introchem/chapter/the-alkaline-earth-metals The alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure. All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge. All of the alkaline earth metals except magnesium and strontium have at least one naturally occurring radioisotope.
