The correct formula for iron (II) phosphide is a. Fe\u2083P\u2082<\/strong>.<\/p>\n\n\n\n

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

To determine the correct formula for iron (II) phosphide, we need to consider the oxidation states of the elements involved, iron (Fe) and phosphorus (P), and use these to form a neutral compound.<\/p>\n\n\n\n

    \n
  1. Iron (II):<\/strong> The Roman numeral (II) in the name “iron (II) phosphide” indicates that iron has an oxidation state of +2. This means that for each iron (Fe) atom, there is a charge of +2.<\/li>\n\n\n\n
  2. Phosphorus:<\/strong> Phosphorus, as an element in group 15 of the periodic table, typically forms an anion with a charge of -3. This is because phosphorus tends to gain three electrons to achieve a stable electron configuration, resulting in the phosphate ion, ( P^{3-} ).<\/li>\n<\/ol>\n\n\n\n

    To form a neutral compound, the total positive charge from the iron atoms must balance out the total negative charge from the phosphorus atoms. Here’s how we determine the correct ratio:<\/p>\n\n\n\n

      \n
    • The charge from iron is +2 per atom, and the charge from phosphorus is -3 per atom.<\/li>\n\n\n\n
    • The least common multiple (LCM) of 2 (from iron) and 3 (from phosphorus) is 6. To balance the charges, we need three iron (Fe) atoms to provide a total positive charge of ( 3 \\times +2 = +6 ), and two phosphorus (P) atoms to provide a total negative charge of ( 2 \\times -3 = -6 ).<\/li>\n<\/ul>\n\n\n\n

      Thus, the correct formula is Fe\u2083P\u2082<\/strong>, where three iron atoms combine with two phosphorus atoms to form a neutral compound. This is the formula for iron (II) phosphide.<\/p>\n\n\n\n

      Other Choices:<\/h3>\n\n\n\n
        \n
      • b. Fe\u2082P\u2083<\/strong>: This would imply an oxidation state of +3 for iron, but the compound is iron (II), meaning the oxidation state of iron should be +2.<\/li>\n\n\n\n
      • c. FeP<\/strong>: This formula would suggest a 1:1 ratio of Fe and P, which is incorrect based on their respective oxidation states.<\/li>\n\n\n\n
      • d. Fe\u2082P<\/strong>: This formula would not balance the charges correctly for iron (II) and phosphorus (P).<\/li>\n\n\n\n
      • e. FeP\u2082<\/strong>: This would imply two phosphorus atoms for every iron atom, which would not balance the charges of +2 for iron and -3 for phosphorus.<\/li>\n<\/ul>\n\n\n\n

        Thus, the correct answer is a. Fe\u2083P\u2082<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
