4
Atomic Basics Focus on outer electrons Metals-left Nonmetals-right
5
Bonding Basics Ionic Bond Covalent Bond Metal / nonmetal Creates ions
Give/take electrons Covalent Bond 2+ nonmetals No ions Share electrons
6
PROCESS BOX 2-1 Despite the fact that ionic bonding and covalent bonding treat their electrons very differently, what similarities do they have in regard to the end result? 3 LINE MINIMUM!
7
Other forces Polar covalent bonds Hydrogen Bonds Van der Waals Forces
Uneven sharing of electrons Hydrogen Bonds H and O or N Van der Waals Forces Very weak bonds Only close contact
8
Bonding
9
PROCESS BOX 2-2 The vast majority of compounds in your body are made of the elements C,H,O,P,S, and N. Is most of our body the result of ionic or covalent bonds? Explain. 3 LINE MINIMUM!
11
Properties of Water Water has 6 important properties Polarity
Hydrogen bonding Adhesion Cohesion Universal Solvent High Specific Heat
12
Water Properties Foldable
For each of the following 6 properties of water you will be expected to: Label the Property Draw a Picture depicting that property Define or describe that property Explain why that property is important to life Your foldable is to be constructed in the following way: Fold two pieces of paper longwise (landscape orientation or “hotdog fold”). Staple them together as close to the top as possible

14
PROCESS BOX 2-3 Pick two of the water properties discussed and explain how we simply could not function/exist without them 4 LINE MINIMUM!
15
The pH Scale Reads from 0-14 Measures [H+] Mastery?
0-7 acid; 7 neutral; 8-14 base Acid Base Neutral Mastery?
16
PROCESS BOX 2-3 Our body needs to be between a pH of 6.5 and 7.5 to normally function. How can you eat a grapefruit for breakfast and not get ill? 2 LINE MINIMUM!
17
DEHYDRATION SYNTHESIS
HYDROLYSIS MONOMERS and POLYMERS MONOMER POLYMER
