Question

name the following ionic compound: lino₃
a lithium nitride
b lithium oxide
c lithium iii nitrate
d lithium nitrate

Explanation:

Ionic compounds are named by stating the cation first, followed by the anion. In \( \text{LiNO}_3 \), \( \text{Li}^+ \) is the lithium cation. \( \text{NO}_3^- \) is the nitrate anion.

• Option a: Lithium nitride would be \( \text{Li}_3\text{N} \) as nitride is \( \text{N}^{3 - } \).
• Option b: Lithium oxide is \( \text{Li}_2\text{O} \) since oxide is \( \text{O}^{2 - } \).
• Option c: Lithium has a fixed charge of \( + 1 \) in its compounds, so the Roman numeral III (which implies a \( + 3 \) charge) is incorrect.
• Option d: Correctly names the compound as lithium (for \( \text{Li}^+ \)) nitrate (for \( \text{NO}_3^- \)).

Answer:

d. lithium nitrate
