6장, 문제 26a
Write the symbol for the cation in each of the following ionic compounds:
a. FeCl2
검증된 단계별 안내1
Identify the chemical formula of the compound: FeCl₂. This indicates that the compound contains iron (Fe) and chloride (Cl) ions.
Determine the charge of the chloride ion (Cl⁻). Chloride is a halogen and typically forms a -1 charge as an anion.
Since there are two chloride ions in FeCl₂, the total negative charge contributed by the chloride ions is -2 (2 × -1 = -2).
To balance the overall charge of the compound (which must be neutral), the iron (Fe) cation must have a charge of +2 to counteract the -2 charge from the chloride ions.
Write the symbol for the cation, including its charge: Fe²⁺.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Ionic Compounds
Ionic compounds are formed when atoms transfer electrons, resulting in the formation of charged ions. Typically, a metal atom loses electrons to become a positively charged cation, while a non-metal atom gains electrons to become a negatively charged anion. The electrostatic attraction between these oppositely charged ions holds the compound together.

Naming Ionic Compounds
Cations and Anions
Cations are positively charged ions that result from the loss of one or more electrons, while anions are negatively charged ions formed by the gain of electrons. In ionic compounds, cations are usually metals, and anions are non-metals or polyatomic ions. Understanding the charge and identity of these ions is crucial for writing the correct formulas and symbols for ionic compounds.

Oxidation States
Oxidation states indicate the degree of oxidation of an atom in a compound, reflecting the number of electrons lost or gained. In the case of FeCl₂, iron (Fe) can have multiple oxidation states, but in this compound, it has an oxidation state of +2. Recognizing the oxidation state helps in determining the correct symbol for the cation, which in this case is Fe²⁺.
