The given matching exercise involves identifying various chemical species, including ions, compounds, and elements, based on their characteristics such as electron configuration, composition, and type. The task is to correctly associate each item with its corresponding description or category, which requires an understanding of chemical nomenclature, electron counts, and the properties of elements and ions.


First, let us examine each item and deduce its correct match. Starting with item 1, FeBr₂, which is iron(II) bromide, a transition metal compound. Item 2, S²⁻, is the sulfide anion. Item 3, NH₄⁺, is ammonium, a polyatomic cation. Item 4, SO₃²⁻, is the sulfite anion, and item 5, Ca, is calcium, an alkaline earth metal. Item 6, FeBr₃, is iron(III) bromide, another transition metal compound. Item 7, SO₄²⁻, is sulfate, a polyatomic anion. Item 8, Be, is beryllium, an alkaline earth metal. Item 9, Co, is cobalt, a transition metal. Item 10, SO₄²⁻, is again sulfate, but it seems it was already matched with item 7. Item 11, Li, is lithium, an alkali metal. Item 12, Ne, is neon, a noble gas, but since the list includes sulfide (l) or sulfite (a), the appropriate match for noble gas is not necessary here; perhaps 'Ne' is just another element in the list.


Now, the keys to decoding are as follows:
  • a) sulfite anion - matches with SO₃²⁻ (item 4), which is sulfur with a 3- oxidation state and 8 electrons around sulfur similar to chloride.
  • b) electron-dot symbol - refers to the notation used to depict valence electrons, matching items like Ne (a noble gas with full valence shell) or S²⁻ (which has 8 electrons in its valence shell).
  • c) alkali metal - matches with lithium (Li), an alkali metal.
  • d) has the same electron configuration as Na⁺ - applies to species with 11 electrons like Na⁺ and to ions with 10 electrons, such as Ne (neon).
  • e) iron (II) bromide - matches with FeBr₂.
  • f) transition metal - applies to Fe (iron) and Co (cobalt).
  • g) sulfate anion - matches with SO₄²⁻.
  • h) alkaline earth metal - matches with Be (beryllium) and Ca (calcium).
  • i) has the same electron configuration as Cl⁻ - chlorine ion, which has 17 electrons, so matches with Cl⁻ or species equivalent to Cl⁻.
  • j) iron (III) bromide - matches FeBr₃.
  • k) polyatomic cation - matches with NH₄⁺ (ammonium).
  • l) sulfide anion - matches with S²⁻.

Based on the above, the full matches are as follows:

  1. FeBr₂ - e) iron (II) bromide
  2. S²⁻ - l) sulfide anion
  3. NH₄⁺ - k) polyatomic cation
  4. SO₃²⁻ - a) sulfite anion
  5. Ca - h) alkaline earth metal
  6. FeBr₃ - j) iron (III) bromide
  7. SO₄²⁻ - g) sulfate anion
  8. Be - h) alkaline earth metal (beryllium)
  9. Co - f) transition metal (cobalt)
  10. SO₄²⁻ - g) sulfate anion (already matched)
  11. Li - c) alkali metal (lithium)
  12. Ne - b) electron-dot symbol (representative of a noble gas with full valence electrons)

In conclusion, the matching exercise requires understanding of atomic structure, ion types, and chemical nomenclature to correctly categorize each component based on its properties and relationships to other elements or ions.
