Unit 6: Chemical Bonds

Unit 6 Focuses on Chemical Bonds

Chapters 18&19

Learning Objectives for Students:
1. Build models of atoms
2. Understand how atoms of each element differ
3. Describe the forces that hold an atom together
4. Understand how elements are organized in the periodic table
5. Use the periodic table to identify the atomic number and mass numbers of each element
6. Relate the chemical behavior of an element, including bonding, to its placement on the periodic table
7. Explain how elements form chemical bonds and identify the role of electrons in bonding

CA State Standards Addressed in this unit:

CA- California K-12 Academic Content Standards
Subject : Science
Grade : Grades Nine Through Twelve
Area : Chemistry
Sub-Strand : Chemical Bonds
Concept 2: Biological, chemical, and physical properties of matter result from the ability of atoms to form bonds from electrostatic forces between electrons and protons and between atoms and molecules. As a basis for understanding this concept:
a: Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.
b: Students know chemical bonds between atoms in molecules such as H 2 , CH 4 , NH 3 , H 2 CCH 2 , N 2 , Cl 2 , and many large biological molecules are covalent.
c: Students know salt crystals, such as NaCl, are repeating patterns of positive and negative ions held together by electrostatic attraction.
d: Students know the atoms and molecules in liquids move in a random pattern relative to one another because the intermolecular forces are too weak to hold the atoms or molecules in a solid form.
e: Students know how to draw Lewis dot structures.
f: Students know how to predict the shape of simple molecules and their polarity from Lewis dot structures.
