What is the charge on the barium ion? (The symbol for barium is Ba)<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The charge on the barium ion (Ba) is +2<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Barium is an alkaline earth metal, located in Group 2 of the periodic table. Elements in Group 2 typically form ions by losing two electrons to achieve a stable electron configuration, similar to the nearest noble gas. To understand why barium forms a +2 ion, let\u2019s explore its atomic structure.<\/p>\n\n\n\n

Atomic Structure of Barium:<\/h4>\n\n\n\n
    \n
  • Atomic number of barium (Ba)<\/strong>: 56. This means barium has 56 protons and 56 electrons in its neutral state.<\/li>\n\n\n\n
  • Electron configuration<\/strong>: The electron configuration of barium is:
    [
    [Xe] 6s^2
    ]
    where [Xe] represents the electron configuration of xenon (the noble gas preceding barium in the periodic table), and the “6s\u00b2” indicates that barium has two electrons in its outermost (6th) shell.<\/li>\n<\/ul>\n\n\n\n

    Tendency to Lose Electrons:<\/h4>\n\n\n\n

    Barium, as an element in Group 2, has two electrons in its outermost shell (the 6s orbital). In order to achieve a more stable electron configuration, similar to the nearest noble gas (xenon), barium tends to lose these two valence electrons. By losing these electrons, barium’s electron configuration becomes:<\/p>\n\n\n\n

    [
    [Xe] \\quad \\text{(core configuration, no electrons in the outer shell)}
    ]<\/p>\n\n\n\n

    After losing two electrons, barium has a net positive charge because it now has more protons (56) than electrons (54). The result is a barium ion with a charge of +2<\/strong>.<\/p>\n\n\n\n

    Why the +2 Charge?<\/h4>\n\n\n\n
      \n
    • The removal of two negatively charged electrons leaves the barium ion with a positive charge.<\/li>\n\n\n\n
    • The resulting barium ion is symbolized as ( \\text{Ba}^{2+} ), indicating that it has a 2+ charge.<\/li>\n<\/ul>\n\n\n\n

      This behavior is typical for alkaline earth metals, such as magnesium (Mg), calcium (Ca), and strontium (Sr), all of which form ions with a +2 charge. The +2 charge helps these elements attain a more stable electronic structure.<\/p>\n","protected":false},"excerpt":{"rendered":"
