- Ionic compounds are easily recognized because they contain a metal and a nonmetal. Covalent compounds are those which contain only nonmetals. The periodic table in the front cover of your text shows which elements fall into each class. The names for ionic compounds are very simple. The first part of the name is simply the name of the metal element. The second part of the name is the name of the nonmetal element, with the ending changed to the suffix –ide. For example, consider the compound Al 2 O 3. While the subscripts indicate that the compound consists of two atoms of aluminum and three atoms of oxygen, these numbers do not affect the name. The first part of the name would be aluminum. For the second part of the name, we drop the ending on oxygen and add –ide, thus it becomes oxide. The name of the compound is then aluminum oxide. When an ionic compound contains a transition metal, the names become a bit more complicated. The metals in the d and f blocks can have more than one charge and can thus form more than one compound. For example, iron and chlorine form two different compounds, FeCl 2 and FeCl 3. To distinguish them,

Formulas and Nomenclature of Ionic and Covalent Compounds Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms, in the case of polyatomic ions) gains or loses electrons. 1  A cation is a positively charged ion.  An anion is a negatively charged ion.

- In chemistry, an ionic compound is a chemical compound in which ions are held together in a structure by electrostatic forces termed ionic bonds.The positively charged ions are called cations and the negatively charged ions are called anions.onic compounds without the acidic hydrogen ion (H +), or the basic ions hydroxide (OH −) or oxide (O 2−), are also known as salts and can be formed by acid-base reactions.

General Chemistry 2.8 The cation is always named first and the anion second. 2. A simple cation (obtained from a single atom) takes its name from the name of the element. Include a Roman numeral to indicate the oxidation number (charge) on the metal cation. 3. A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding the letters IDE. 4. Write the name for the compound by combining the names of the ions.

Nomenclature of Binary Ionic Compounds Containing a Metal Ion With a Fixed Charge Rules for Naming Binary Ionic Compounds Containing a Metal Ion With a Fixed Charge. A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal. For example, sodium iodide, NaI, is composed of sodium ions, Na+ (elemental sodium is a metal), and iodide ions, I- (elemental iodine is a nonmetal). Rule 1.

Ionic compound The purple spheres represent sodium cations, Na+, and the green spheres represent chloride anions, Cl−. In chemistry, an ionic compound is a chemical compound comprising ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic species such as the ammonium (NH+.

How to Write Ionic Compounds Positive ions (or cations) and negative ions (anions) can combine to form an ionic compound that is once again electrically neutral. These ionic compounds are named according to strict rules, so once you learn them, it's always possible to write the compound's chemical formula.

- Writing Chemical Formulas of Ionic Compounds. 1  1. Identify the chemical symbols for the cations and anions. All chemicals have what you can call a first and last name. 2  2. Recognize polyatomic ions. Sometimes the cation or anion is a polyatomic ion. 3  3. Determine the valence charge of each element.

Practical 1- Chemistry How do names of covalent compounds differ from the names of ionic compounds. Ionic compounds- Cation is named first, followed by the anion. If an ionic compound is formed with a transition metal and there are more than 1 possibleions that can be present there are two ways to name the compound (systematic and common).

Chemical Principles/Atoms, Molecules, and Ions Simple anions made by adding electrons to single atoms have names ending in-ide, as chloride, Cl - , and sulfide, S 2- , ions. For complex ions of a nonmetal atom with oxygen, the higher and lower oxidation state ions are differentiated by the suffixes-ate and-ite. The oxidation state of a metal cation (see Chapter 10) is indicated by a Roman numeral after the name of the metal, as in Fe 3+ , iron(III), or by the suffixes-ic and-ous.

- Method 1 Naming Ionic Compounds. 1. Know what makes a compound ionic. Ionic compounds contain a metal and a nonmetal. Refer to the periodic table of elements to see what categories the elements in the compound belong to. 2. Build the name. For a two element ionic compound, the naming is simple. The first part of the name is the name of the metal element.

Binary Ionic Compounds Containing a Metal Ion With a Variable Charge Rule 1. The positive ion (cation) is written first in the name; the negative ion (anion) is written second in the name. Rule 2. The name of the cation is the same as the name of the (neutral metal) element from which it is derived. The charge on the cation is indicated using a Roman numeral, within parentheses, immediately following the name of the cation (e.g., Fe 3+ = iron(III), Fe 2+ = iron(II)). Rule 3.

Key Concepts Some ionic compounds incorporate water molecules in their structure. These compounds are called hydrates. To name the hydrates, the number of waters of hydration is indicated by a Greek prefix following the name of the compound. For example, CuSO 4 · 5H 2 O is called copper(II) sulfate pentahydrate. Determining the molecular formula from the compounds name is not always straightforward. This is because the number of cations and anions in a molecule is not specified in the name of an ionic compound.
