Bariu este un metal alcalino-pământos solid, paramagnetic, care cristalizează într-o rețea cubică, cu fețe centrate. Culoarea alb-argintie a bariului metalic devine în contact cu aerul gri mat, deoarece oxidează la suprafață. (vezi poza) Bariu generează o flacără de culoare verde cu liniile spectrale caracteristice de 524,2 și ...

Barium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of molten baryta (BaO). Barium is never found free in nature since it reacts with oxygen in the air, forming barium oxide (BaO), and with water, forming barium hydroxide (Ba(OH) 2) and hydrogen gas (H 2).Barium is most commonly found as the mineral barite (BaSO 4) …

Occurrence. Barium is 14 th most abundant element in earth crust. Its abundance is estimated about 0.05%. in nature, barium mostly occurs in combination with sulfur, oxygen and carbon. The most common source of barium is barite and witherite.

What is Barium. Belonging to the family of alkaline earth metals, barium (pronounced as BAR-ee-em) is a heavy metal represented by the chemical symbol Ba [1].Out of the thirty-seven isotopes of barium, only seven are naturally-occurring ones with mass numbers ranging from 130 to 138 (excluding Ba-131) where barium-133 is the most stable, having a half-life of 10.51 years [4].

Barium is the 56th element in the periodic table and has a symbol of Ba and atomic number of 56. It has an atomic weight of 137.327 and a mass number of 138.
