The fraction but all the same does not have many uses, but when combine with opposite elements it becomes quite useful. Located in the alkaline earthly fretting metal group, barium has an atomic number of 56 and has an atomic mass of 137.327. The mass is make up of 56 protons and 81 neutrons. There are 6 energy levels of negatrons that total 56 and have the S, P, and D orbitals. The electron configuration of atomic number 56 is 1s2 2s2p6 3s2p6d10 4s2p6d10 5s2p6 6s2 and is a metallic element that is a soft powder and is silvery white like transmit when pure. It also oxidizes very easygoing and it can be decomposed with peeing or alcohol. The density Barium is 3.51 g/cm3 when at 293K and it has a melting point at 998.2 K and boils at 2123 K. Barium was discover and accepted as an element by Sir Humphrey Davy in 1808 when he also find magnesium, calcium, and strontium. The world-class person who really discovered it was Steele in 1774 when he down a new element in Bononian phosphorus and manifold it from the original element, but Davy recognized it as an element.
