Question

question 2. drag the correct name of each cation or anion to match its chemical formula listed below.
a. na⁺
b. cl⁻
c. mn²⁺
d. mn⁴⁺
e. o²⁻
possible points: 33.33
options: sodium(i) ion, sodium ion, sodiumide ion, chlorine(i) ion, chloride ion, chlorine ion, manganese ion, manganese(ii) ion, manganide ion, manganese(iv) ion, oxygen ion, oxygen(ii) ion, oxide(ii) ion, oxide ion

Explanation:

• For \( \text{Na}^+ \): Sodium has a common +1 charge, so it's named Sodium ion (or Sodium(I) ion, but "Sodium ion" is more standard for the +1 cation of sodium).
• For \( \text{Cl}^- \): The anion of chlorine is called Chloride ion (since halogens form -ide anions, \( \text{Cl}^- \) is chloride).
• For \( \text{Mn}^{2+} \): Manganese with a +2 charge is Manganese(II) ion (the Roman numeral indicates the oxidation state).
• For \( \text{Mn}^{4+} \): Manganese with a +4 charge is Manganese(IV) ion (Roman numeral for oxidation state +4).
• For \( \text{O}^{2-} \): The anion of oxygen with -2 charge is Oxide ion (oxygen forms oxide as the -ide anion with -2 charge).

Answer:

a. \( \text{Na}^+ \): Sodium ion (or Sodium(I) ion)
b. \( \text{Cl}^- \): Chloride ion
c. \( \text{Mn}^{2+} \): Manganese(II) ion
d. \( \text{Mn}^{4+} \): Manganese(IV) ion
e. \( \text{O}^{2-} \): Oxide ion
