1. Chemical Bonding
-A chemical bond is the attraction between atoms that holds them together.
-the negatively charged electrons and positively charged nuclei are involved in bonding.
-There are three different kinds of bonds that are important to know. They are:
1. ionic
2. covalent
3. metallic

3. Chemical Bonding Ionic Bonds -between metals and nonmetals
-doesn’t conduct electricity except when in water
-metal gives up electrons completely to nonmetal
-metal is called “cation”
-nonmetal is called “anion”

4. Chemical Bonding

5. Chemical Bonding Covalent Bonds -between nonmetals only
-never conducts electricity
-sharing of electrons

6. Chemical Bonding

7. Chemical Bonding Metallic Bonds -between metals only
-conducts electricity
-protons surrounded by a “sea” of electrons

8. Chemical Bonding Analogies
Develop your own analogy for the 3 chemical bonds (ionic, covalent, and metallic). Draw a single panel cartoon for each and explain how each cartoon is like the chemical bond.
Remember: covalent bonds share electrons
ionic bonds give and take electrons
metallic bonds are like a sea of electrons
