Recognize polyatomic ions in chemical formulas. We have already encountered some chemical formulas for simple ionic compounds. A chemical formula A concise list of the elements in a compound and the ratios of these elements.
Metal cation has more than one possible charge. Naming Ionic Compounds Most ionic compounds are binary ionic compounds, substances that consist of just two different ions derived from two different elements—one metal and one nonmetal. An ionic compound is named using the name of the cation followed by the name of the anion, eliminating the word ion from each.
Several examples were given in the Formulas of Ionic Compounds section.
In cases where a metal cation may have more than one possible charge, recall that the charge is indicated in the name of the ion with a Roman numeral in parentheses. Strategy Begin by identifying the cation and the anion in each compound, and then combine the names for each, eliminating the word ion.
Think About It Be careful not to confuse the subscript in a formula with the charge on the metal ion. In part cfor example, the subscript on Fe is 2, but this is an iron III compound. Practice Problem A Name the following ionic compounds: Practice Problem B Name the following ionic compounds: Strategy Identify the ions in each compound, and determine their ratios of combination using the charges on the cation and anion in each.
In order to produce a neutral compound, these two ions must combine in a 1: These ions also combine in a 1: These ions combine in a 3: Think About It Make sure that the charges sum to zero in each compound formula. Practice Problem A Deduce the formulas of the following ionic compounds: Practice Problem B Deduce the formulas of the following ionic compounds: When compounds form between elements with more similar properties, electrons are not transferred from one element to another but instead are shared in order to give each atom a noble gas electron configuration.
It was Gilbert Lewis who first suggested that a chemical bond involves atoms sharing electrons, and this approach is known as the Lewis theory of bonding.
This type of arrangement, where two atoms share a pair of electrons, is known as covalent bonding, and the shared pair of electrons constitutes the covalent bond.
In a covalent bond, each electron in a shared pair is attracted to the nuclei of both atoms. It is this attraction that holds the two atoms together.
For the sake of simplicity, the shared pair of electrons can be represented by a dash, rather than by two dots: Molecules The formation of a covalent bond between two H atoms produces a species known as a molecule. A molecule is a neutral combination of at least two atoms in a specific arrangement held together by chemical forces also called chemical bonds.
A molecule may contain two or more atoms of a single element, or it may contain atoms of two or more elements joined in a fixed ratio. Thus, a molecule can be of an element or it can be of a compound, which, by definition, is made up of two or more elements.~,Write Lewis symbols for atoms and ions.
