The ion therefore has 54 Electrons and emulates the Electron configuration of the Noble Gas 'Xenon' (Xe). The Barium is a very big 'thing' compared to an electron. In the case of Barium the abbreviated electron configuration is [Xe] 6s2. The lewis structure of the ion of barium has no dots and a 2 charge. Barium is an alkaline earth metal that has 2 outer electrons in its 6s shell. Calcium is also part of this group. Finding Valence Electrons for All Elements Except Transition Metals. Barium has 81 neutrons, along with 56 protons and 56 electrons… Electrons have a specific form of distribution (or configuration) in every atom, even Barium. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. It is a very reactive chemical that is often silver-white yellowish in color. was asked on May 31 2017. Barium Atomic Structure Stock Image C018 3737 Science An electron can compress itself and 836592 electrons can fit inside a barium. Accordingly, valence electrons directly influence how elements behave in a chemical reaction. Chlorine gets 7 dots. It has no valence electrons. If the outermost orbit of an atom is complete with eight electrons, it is stable chemically. Well, you will always have access to a Periodic Table, and the "Group Number", the vertical column in which the metal lies is "Group 2". How do you find the Valency of barium? So, barium has a theoretical valency of 2, and it actually has this valency in BaCl2 and BaSO4. They do not have the same number of valence electrons like Calcium. It reacts in water and forms hydroxide.
