Recall that the noble gases, the elements found in Group 18 or8A, are naturally stable, because they inherently possessan octet of valence electrons. Explanation: Rb atom has 37 electrons and 37 protons. Furthermore, since all subsequent procedural steps are dependent on that initial valence electron count,all elements in the same group will gain or lose the same number of electrons to achieve an octet configuration. Rubidium (an alkali metal) does not form compounds or ionic bonds with calcium (an alkaline earth metal). Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. 1. the ratio of each kind of ion in the compound. Barium gives one electron to a chlorine atom and another electron to another chlorine atom, as valency of chlorine is 1, so it is $\ce{BaCl2}$. This combination is written as \(\ce{AlF3}\). #BaO# is the likely formula. Therefore, "-ate" and "-ite" suffixes are employed, in order to denote that the corresponding polyatomic ions are part of a series. Webbarium (Ba), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table. Rubidium, particularly vaporized 87Rb, is one of the most commonly used atomic species employed for laser cooling and BoseEinstein condensation.
