Facts, pictures, stories about the element Barium in the ...

As an alkali earth, barium is reactive enough that it must be kept under oil to prevent rapid deterioration into barium oxide. I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of. Source: David Franco

Electrode Potential and Galvanic Corrosion

The potential difference between an anode and a cathode can be measured by a voltage measuring device but since the absolute potential of an anode or cathode cannot be measured directly - all potential measurements are made against a standard electrode. The standard electrode potential is set to zero and the measured potential difference can be considered as absolute.

Barium - Wikipedia

Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.Because of its high chemical reactivity, barium is never found in nature as a free element.Its hydroxide, known in pre-modern times as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.
