Which formulas represent one ionic compound and one molecular compound.

Covalent bonds are shown using lines. The number of dashes indicate whether the bond is a single, double, or triple covalent bond. Structural formulas are helpful because they explain the properties and structure of the compound which empirical and molecular formulas cannot always represent. Ex. Structural Formula for Ethanol:Polyatomic ions. In this article, we will discuss polyatomic ions. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text {Na}^+ Na+, \text {Fe}^ {3+} Fe3+, \text {Cl}^- Cl−, and ...Polyatomic ions. In this article, we will discuss polyatomic ions.

Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other. Created by Sal …Ionic compounds are composed of positive and negative ions held together by ionic bonds. An Ionic bond is a type of bond that forms between a metal and a non-metal. Molecular compounds are compounds made up of nonmetals. A covalent bond is a type of bond that occurs between two nonmetals.An ionic formula, like \(\ce{NaCl}\), is an empirical formula. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. Sodium sulfide, another ionic compound, has the formula \(\ce{Na_2S}\). This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions.Figure 3.1.3 3.1. 3: The Three-Dimensional Structures of Water, Ammonia, and Methane. (a) Water is a V-shaped molecule, in which all three atoms lie in a plane. (b) In contrast, ammonia has a pyramidal structure, in which the three hydrogen atoms form the base of the pyramid and the nitrogen atom is at the vertex.Ionic and molecular compounds are named using somewhat-different methods. Binary ionic compounds typically consist of a metal and a nonmetal. The name of the metal is written first, followed by the name of the nonmetal with its ending changed to – ide. For example, K 2 O is called potassium oxide.
