% of Test by Goal & Objective

• 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.

NC Final Exams in High School

Science contains a total of 45 MC items.

The total time allocated to the test is

120 minutes unless students have documented accommodations.
