Purpose
Bonds form between atoms to achieve stability and the properties of an element at the atomic level
explain bonding behavior. In this section, we will learn about different types of bonds, how to represent
bonds between atoms, and the molecular geometry associated with different types of bonding patterns.

Essential Understandings
The concepts developed in this standard include the following:

Lewis dot diagrams are used to represent valence electrons in an element. Structural
formulas show the arrangements of atoms and bonds in a molecule and are
represented by Lewis dot structures.

Bonds form between atoms to achieve stability. Covalent bonds involve the sharing of
electrons between atoms. Ionic bonds involve the transfer of electrons between ions.
Elements with low ionization energy form positive ions (cations) easily. Elements with
high ionization energy form negative ions (anions) easily. Polar bonds form between
elements with very different electronegativities. Non-polar bonds form between
elements with similar electronegativities.

Polar molecules result when electrons are distributed unequally.
Knowledge, and Skills
In order to meet this standard, it is expected that students will

predict, draw, and name molecular shapes (bent, linear, trigonal planar, tetrahedral,
and trigonal pyramidal).

draw Lewis dot diagrams to represent valence electrons in elements and draw Lewis
dot structures to show covalent bonding.

use valence shell electron pair repulsion (VSEPR) model to draw and name molecular
shapes (bent, linear, trigonal planar, tetrahedral, and trigonal pyramidal).

recognize polar molecules and non-polar molecules.
