Iron sulfide is the chemical compound FeS, a black solid., When metallic iron (oxidation state 0) is placed in a solution of hydrochloric acid, iron (II) chloride is formed,with release of hydrogen gas, by the reaction. When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. Hg 2 2+ Mercury This is why the formula is CaCl_2, because two anions in here are needed to balance the charge from the cation. Write the cation symbol followed by anion symbol. 0000004802 00000 n Large sized anions occupy lattice sites, while small sized cations are found in voids. When an anion (an ion with a negative charge) attracts a cation (an ion with a positive charge) through electrostatic forces, then an ionic compound is formed. In the first compound, the iron ion has a 2+ charge because there are two Cl − ions in the formula (1− charge on each chloride ion). In this case, you know that you have ammonium, NH+ 4, as the cation. Our experts can answer your tough homework and study questions. What is the compound formula for Cation: Na+ and Anion: CN- Chemistry. {/eq}. ZnO 7. For an overall anion charge of -4, iron must have a +2 oxidation state. © copyright 2003-2021 Study.com. These are two different compounds that need two different names. In other words, The total number of Positive charge on the cation = The total number of Negative charge of the anion 0000004780 00000 n In this case, you know that you have the carbonate ion, CO2− 3, as the anion. Ca(NO2)2 I don't need cation and anion of this, just the compound formula of this please 8. Compound Name: Formula: Cation: Anion: lithium fluoride: LiF: Li + F-sodium chloride: NaCl: Na + Cl-calcium chloride: CaCl 2: Ca 2+ Cl-iron(II) oxide: FeO: Fe 2+ O 2-aluminum sulfide: Al 2 S 3: Al 3+ S 2-iron(III) sulfate: Fe 2 (SO 3) 3: Fe 3+ SO 3 2- strong electrolyte . P2O3 4. The order for names in a binary compound is first the cation, then the anion… 0000002141 00000 n 0000001504 00000 n {/eq} Therefore, the chemical formula of magnesium carbonate is {eq}{\text{MgC}}{{\text{O}}_{\text{3}}} When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each. ff��ȥm��ѝ�*��"Z�8=��T�M)w��Gs The formula of the compound is : {/eq} and the anion is {eq}{\text{C}}{{\text{l}}^{\text{ - }}}. As such, the cation in this compound is sodium ion while the anion is the chloride ion. Please give me the Cation and Anion Formula, the simple one like Zn+ and O- and please give me its compound name, thanks guys. Chemistry. The formula for lithium sulfate is _____. 0000009992 00000 n {/eq}, Magnesium is an alkaline earth metal and it loses 2 electrons to form {eq}{\text{M}}{{\text{g}}^{{\text{2 + }}}}. 0000005785 00000 n The charge of a cation or anion is denoted as a superscript after the formula of the ion. it contains 70.5% carbon, 11.5% hydrogen, Name. The overall ionic formula for a compound must be electrically neutral, meaning it has no charge.

An ionic formula, like \(\ce{NaCl}\), is an empirical formula. The charge on cation M is + 2 and anion A is − 3. A cation which exhibits a positive charge is denoted with a superscript + after the name of the element or chemical formula of a compound, e.g., Fe2+ and NH4+. By convention, the first ion in an ionic compound is the cation while the next one is the anion. 0000010977 00000 n An example of a formula that includes water of hydrate is that of copper (II) sulfate pentahydrate. Cations and anions introduction: Ions which are a part of the science subject Chemistry forms from atoms and electrons that have either gained or lost their weight by the removal or adding of one or more valence electrons which would create either positive or a negative charge. soluble ionic compound. Write the correct formula for a compound formed from these ions and name the compound using the IUPAC nomenclature rules. which many ions are closely packed, arranged so that cation/anion attractions are maximised and anion/anion repulsions are minimised. 0000062354 00000 n Expert Answer . _____ Part C 3. Likewise, the cation is added first to the compound's chemical formula. 0000059597 00000 n Ag+ I-CoF2.
