교과서 질문
Write the formula for the polyatomic ion and name each of the following compounds: d. Fe(HCO₃)₃
검증된 단계별 안내1
Identify the polyatomic ion in the compound. In this case, it is the bicarbonate ion, \( \text{HCO}_3^- \).
Recognize that \( \text{Fe} \) is the symbol for iron, and it is combined with the bicarbonate ion.
Determine the charge of the iron ion. Since there are three bicarbonate ions, each with a charge of \(-1\), the total negative charge is \(-3\). Therefore, the iron must have a charge of \(+3\) to balance the charges.
Name the iron ion based on its charge. Iron with a \(+3\) charge is called iron(III).
Combine the names of the cation and the anion to name the compound: iron(III) bicarbonate.

Polyatomic Ions
Polyatomic ions are ions composed of two or more atoms covalently bonded together, which carry a net charge. Common examples include carbonate (CO₃²⁻) and bicarbonate (HCO₃⁻). Understanding polyatomic ions is essential for writing chemical formulas and naming compounds, as they often appear in various chemical reactions and compounds.

Chemical Formulas
A chemical formula represents the composition of a compound, indicating the types and numbers of atoms present. In the case of Fe(HCO₃)₃, the formula shows that one iron (Fe) atom is combined with three bicarbonate (HCO₃) ions. Recognizing how to interpret and construct chemical formulas is crucial for identifying the components of a compound.
