Review: BondingNew: Titration Lab Experiment
• Atoms, Isotopes & Ions• Subatomic Particles
• Electron configurations• Bohr Model for Radiation
• See Reference Tables• Radioactive Decay & Half-Life
• Objective 1•Goal 1
Balancing Nuclear Equations & Half-Life Problems
How to calculate the number of protons, neutrons and
electrons from the atomic and mass numbers!
• Types of Bonds• Strengths• Properties
• Test for conductivity• Inter vs. Intra molecular forces• Nomenclature
• Objective 2•Goal 1
Flow chart for Intermolecular forces of attraction focus on:
1. dipole-dipole2. London Dispersion forces
3. Hydrogen Bonding
Be sure to know your naming flowchart!
Polyatomic Ions are provided in the Reference Packet!
• Periodic Properties• Periodic Table Locations
• Metals, non-metals, periods, groups
• Atomic Radius• Electronegativity• Ionization Energy
• Objective 3•Goal 1
Be sure to notice the staircase
To separate Metals and Non-metals!
Remember that Fr (Francium) only wins
AR (atomic radius)
• Pressure, Volume & Temperature
• Phase Change calculations• Temperature Change
calculations• Gas Laws• Phase Diagrams
• Objective 1•Goal 2
Organize your gas law problems by using the P V T
n box!
Draw the heating curve on Paper as soon as you get
your test. Be sure to label phase
And temperature changes.
• Reactions & Stoichiometry• Types of reactions• Balance equations• Energy of a reaction• Evidence of chemical change• Empirical vs. Molecular Formula• % composition
• Hydrate calculations
• Objective 2•Goal 2
Use paper to draw your MoleRoadmap as soon as you
start the test!
The types of reactions will be provided for you in the
Reference Packet!
• Reaction Rate & Equilibrium• Factors affecting rate• System @ Equilibrium• Le Chatelier’s Principle
• Objective 1•Goal 3
Know how different stresses will shift equilibrium
Know how to write Keq
• Solutions• Acid vs. Base• Molarity• Titration• Dilution• Solubility Diagrams• Solubility Rules
• Objective 2•Goal 3
There is a lot of vocabulary for this topic!
The Solubility Rules are provided for you in the
Reference Packet.
Why do the first ionization energies of the elements increase going across the periodic table?
A Inner electrons at lower energy levels block the protons’ force of attraction toward the nucleus.
B The atomic radius decreases, and outer electrons are closer and strongly attracted to the nucleus.
C Electrons are further from the nucleus, and it is harder to remove the outermost electron.
D The atomic radius increases, and outer electrons are closer and strongly attracted to the nucleus.
