- 4.3: Formulas for Ionic Compounds
Write the chemical formula for an ionic compound composed of each pair of ions. the sodium ion and the sulfur ion; the aluminum ion and the fluoride ion; the 3+ iron ion and the oxygen ion; Solution. To obtain a valence shell octet, sodium forms an ion with a 1+ charge, while the sulfur ion has a 2− charge.
A quick way to identify acids is to see if there is an H (denoting hydrogen) in front of the molecular formula of the compound. To name acids, the prefix hydro-is placed in front of the nonmetal modified to end with –ic. The state of acids is aqueous (aq) because acids are found in water. Some common binary acids include:
Ions. Made of a single atom: monatomic ion. Made of more than one atom: polyatomic ion. Named by: the name of the element ∙ the word ion or cation. Named by: the root of the name of the element ∙ -ide. EXTENSION Extend the concept map by providing an example of each of the four types of ions.

Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds. In ordinary chemical reactions, the nucleus of each atom (and thus the identity of the element) remains unchanged.
The element name + ion. Some examples are: Na + is the sodium ion and Ca 2+ is the calcium ion. Metals that form cations of more than one possible charge are named as: The element name + roman numeral which indicates the + charge ion. Fe 2+ is the iron (II) ion, and Fe 3+ is the iron (III) ion.
