What would the respective names for the polyatomic ions of phosphorous, PO4 and PO3, be?
A phosphate and phosphite
B phosphate and phosphide<\/p>\n\n\n\n

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

The correct answer is A. phosphate and phosphite<\/strong>.<\/p>\n\n\n\n

Explanation<\/strong>:<\/p>\n\n\n\n

In chemistry, polyatomic ions are ions that consist of two or more atoms covalently bonded, carrying a net charge. For phosphorus-based polyatomic ions, the naming convention changes based on the number of oxygen atoms attached to the phosphorus atom.<\/p>\n\n\n\n

  1. Phosphate (PO\u2084\u00b3\u207b)<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • “Phosphate” is the name for the polyatomic ion with the formula ( \\text{PO}_4^{3-} ).<\/li>\n\n\n\n
    • It has four oxygen atoms bonded to a single phosphorus atom and carries a -3 charge.<\/li>\n\n\n\n
    • The \u201c-ate\u201d suffix is commonly used in naming the most common or typical oxyanion of an element that contains oxygen. In this case, phosphate is the standard oxyanion for phosphorus.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Phosphite (PO\u2083\u00b3\u207b)<\/strong>:<\/li>\n<\/ol>\n\n\n\n
          \n
        • “Phosphite” refers to the polyatomic ion with the formula ( \\text{PO}_3^{3-} ).<\/li>\n\n\n\n
        • This ion has three oxygen atoms bonded to phosphorus, also carrying a -3 charge.<\/li>\n\n\n\n
        • The \u201c-ite\u201d suffix indicates one fewer oxygen atom than the \u201c-ate\u201d form. Phosphite has one less oxygen atom than phosphate but retains the same -3 charge.<\/li>\n<\/ul>\n\n\n\n

          This pattern of naming extends to other elements with polyatomic ions that form oxyanions with different numbers of oxygen atoms. The suffix \u201c-ate\u201d is used for the oxyanion with a relatively higher number of oxygen atoms, while \u201c-ite\u201d is used for the one with fewer oxygen atoms.<\/p>\n\n\n\n

          Common Mistake<\/strong>:
          Some might confuse the terms with \u201cphosphide,\u201d which refers to a different kind of ion. A phosphide ion has the formula ( \\text{P}^{3-} ), containing only phosphorus without any oxygen atoms, and is therefore not a polyatomic ion like phosphate or phosphite.<\/p>\n","protected":false},"excerpt":{"rendered":"
