K₂CrO₄

Answer 1

The compound K₂CrO₄ consists of two potassium ions (K+) and one chromate ion (CrO₄²-).

Step-by-step explanation:

The compound K₂CrO₄ consists of two potassium ions (K+) and one chromate ion (CrO₄²-). The potassium ion has a charge of +1, while the chromate ion has a charge of -2. Therefore, the polyatomic ion in the compound is the chromate ion, CrO₄²-, which carries a charge of -2.
