Chapter 6: Problem 51

Use the following terms to create a concept map: valence electrons, nonpolar, covalent compounds, polar, dipoles, and Lewis structures.

Short Answer

Expert verified
A concept map can be created by correlating valence electrons with covalent compounds and Lewis structures, then differentiating covalent compounds into polar and nonpolar types, with dipoles connected to polar molecules.

Step by step solution

01

Understand the Terms

Start by reviewing the individual terms and their meanings. 'Valence electrons' are the electrons in the outer shell of an atom that participate in chemical bonding. 'Nonpolar' and 'polar' describe the distribution of electrical charge in a molecule. 'Covalent compounds' are substances where atoms share electrons to form a bond. 'Dipoles' are a pair of charges or magnetic poles, of equal magnitude but opposite sign, separated by some distance. 'Lewis structures' are diagrams that show the bonding between atoms and the lone pairs of electrons that may exist in a molecule.
02

Identify Relationships

Consider how these terms are related. For instance, Lewis structures are a means of visualizing the valence electrons involved in covalent bonding, and the sharing of electrons in covalent bonds results in nonpolar or polar molecules, depending on whether the shared electrons are equally or unevenly distributed, respectively. Dipoles are associated with polar molecules.
03

Create the Concept Map

Draw a diagram starting with a central term, say, valence electrons. Branch out to related terms. For example, draw a line from 'valence electrons' to 'covalent compounds' and from 'covalent compounds' to 'Lewis structures'. Then connect 'covalent compounds' to 'polar' and 'nonpolar', and from 'polar' connect to 'dipoles'.
04

Check and Revise

Review the map to make sure all connections and relationships are correctly represented. Amend as necessary.
