Which is the chemical name and formula for a compound containing the elements cesium and phosphorous?
A. cesium phosphorous, Cs3P
B. cesium phosphide, Cs3P
C. cesium triphosphide, CSP3
D. cesium phosphate, CSP3<\/p>\n\n\n\n

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

The correct answer is B. cesium phosphide, Cs\u2083P<\/strong>.<\/p>\n\n\n\n

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

Cesium phosphide is an ionic compound formed from cesium (Cs), a Group 1 alkali metal, and phosphorus (P), a non-metal found in Group 15 of the periodic table. In ionic compounds, metals typically lose electrons to form positive ions (cations), while non-metals gain electrons to form negative ions (anions).<\/p>\n\n\n\n

    \n
  1. Cation and Anion Formation<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • Cesium (Cs)<\/strong> has a valence electron configuration of ([Xe]6s^1), meaning it has one electron in its outermost shell. It readily loses this electron to form a cation, Cs\u207a.<\/li>\n\n\n\n
    • Phosphorus (P)<\/strong>, on the other hand, has a valence electron configuration of ([Ne]3s^23p^3), with five valence electrons. To achieve a stable octet, phosphorus typically gains three additional electrons, forming the phosphide anion, P\u00b3\u207b.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Stoichiometry<\/strong>:<\/li>\n<\/ol>\n\n\n\n
          \n
        • To balance the charge in the compound, three cesium ions (each with a +1 charge) are required to balance one phosphide ion (with a -3 charge). Therefore, the correct stoichiometry leads to the formula Cs\u2083P.<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Misleading Options<\/strong>:<\/li>\n<\/ol>\n\n\n\n
              \n
            • Option A (“cesium phosphorous, Cs\u2083P”) incorrectly names the compound, as it does not reflect the proper naming convention.<\/li>\n\n\n\n
            • Option C (“cesium triphosphide, CSP\u2083”) suggests a different ratio, which does not represent the correct charge balance.<\/li>\n\n\n\n
            • Option D (“cesium phosphate, CSP\u2083”) indicates a compound that would contain additional oxygen atoms (PO\u2084\u00b3\u207b), characteristic of phosphate ions, which is not the case here.<\/li>\n<\/ul>\n\n\n\n

              Thus, cesium phosphide (Cs\u2083P) accurately represents the ionic compound formed between cesium and phosphorus, where the correct name and formula reflect the stoichiometry and the charges of the constituent ions.<\/p>\n","protected":false},"excerpt":{"rendered":"
