Question

complete the following table:
two polyatomic anions
name chemical formula
hypobromite anion
no₂⁻

Explanation:

• For the hypobromite anion: The prefix "hypo -" and the root "brom" (from bromine) with the suffix "-ite" for oxyanions. The chemical formula for hypobromite anion is \( \text{BrO}^- \).
• For \( \text{NO}_2^- \): The root is "nitr" (from nitrogen). The suffix "-ite" indicates the oxyanion with one less oxygen than the "-ate" form. The name of \( \text{NO}_2^- \) is nitrite anion.

Answer:

name	chemical formula
nitrite anion	\( \text{NO}_2^- \)
