atomic basics
Atomic Basics
  • Focus on outer electrons
  • Metals-left
  • Nonmetals-right
bonding basics
Bonding Basics
  • Ionic Bond
    • Metal / nonmetal
    • Creates ions
    • Give/take electrons
  • Covalent Bond
    • 2+ nonmetals
    • No ions
    • Share electrons
process box 2 1
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?

other forces
Other forces
  • Polar covalent bonds
    • Uneven sharing of electrons
  • Hydrogen Bonds
    • H and O or N
  • Van der Waals Forces
    • Very weak bonds
    • Only close contact

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.

properties of water
Properties of Water
  • Water has 6 important properties
    • Polarity
    • Hydrogen bonding
    • Adhesion
    • Cohesion
    • Universal Solvent
    • High Specific Heat
slide12

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

the ph scale
The pH Scale
  • Reads from 0-14
  • Measures [H+]
    • 0-7 acid; 7 neutral; 8-14 base
    • Acid
    • Base
    • Neutral
