An unstable nucleus (radioisotope) releases energy by emitting radiation during
the process of radioactive decay.
Nuclear reactions of a given radioisotope cannot be speed up, slo
The Arithmetic of Equations
Using Balanced Chemical Equations
Chemists use balanced chemical equations as a basis to calculate how much
reactant is needed or product is formed in a reaction.
Stoichiometry = calculatio
Chapter 7 Ionic & Metallic Bonding
Section 7.1 Ions
Valence electrons: electrons in the highest occupied energy level of an elements atom.
To find the number of valence electrons in an atom of a element, simply look at
its group number.
The Mole: A Measurement of Matter
What Is a Mole?
Mole = 6.02 x 1023 particles of a substance
A mole of any substance contains Avogadros #
Particles & Moles
Chemical Names & Formulas
Monatomic ions: consist of a single atom with a positive or negative charge resulting
from the loss or gain of one or more valence electrons.
Cations (metallic elements) tend to lo
Chapter 1 Introduction into Chemistry
Section 1.1 Chemistry
Matter: anything that has mass and occupies space.
Chemistry: study of composition of matter and changes that matter undergoes.
Because living and nonliving things are made of matter, chemistry a
Chapter 5 Electrons in Atoms
Section 5.1 Models of Atom
Development of Atomic Models
Rutherfords atomic model could not explain the chemical properties of elements- it
failed to explain why objects change color when heated.
Energy of an atom
Water & Aqueous Systems
Water & Its Properties
Water In The Liquid State
Water is a triatomic molecule
Oxygen atom covalently bonded to hydrogen(s)
Polar molecule due to its electronegativity (dipole)
Bonding angle is approximately
The Flow of Energy- Heat & Work
Energy = capacity to do work or supplying heat (heat transfer). Energy has neither mass
nor volume and is only detected because of its effects (motion).
Reaction Rates & Equilibrium
Rates of Reaction
Rate = is a measure of the speed of any change that occurs within an interval of time.
In chemistry, the rate of chemical change or the reaction rate is usually expres
Introduction Any chemical reaction involves a changing of energy as heat. The study of this heat exchange is known as Thermochemistry. In lab you used Thermochemistry to determine the change of heat and temperature when NaOH and HCL
Water Quality Analysis Part I and II
Introduction: The objective of the lab experiment was to test the quality of water through various analyzation methods. Water was collected from the same site of the Kansas River on two different occasions and th
Qualitative Analysis Laboratory Goal: To determine the composition of a mixture and decide if the mixture contains one or more reagents. Objective: By following the procedure one can take the several different compounds and run the appropriate experi
1 What Can pH Titration Tell Us? Goal: To determine the molecular weight of unknown acid "D" by adding 0.1 M drops of HCL acid at a time and recording observations of the reaction and the final pH. Objective: By following the procedure, one should be

Chapter 2 Matter & Change
Section 1.1 Properties of Matter
Extensive Properties: property that depends on the amount of a sample
1.) Mass- is a measure of the amount of matter the object contains
2.) Volume- measure of the space occupied
Chapter 4 Atomic Structure
Section 4.1 Defining the Atom
Atom: smallest particle of an element that retains its identity in a chemical reaction
Daltons Atomic Theory:
1.) All elements are composed of atoms
2.) Atoms of the same element are identical
Chapter 6 The Periodic Table
Section 6.1 Organizing the Elements
Chemists used the properties of elements to sort them into groups
Mendeleevs Periodic Table
- Arranged the elements in his periodic table in order of increasing atomic mass
The Meaning of Oxidation & Reduction
What Are Oxidation & Reduction Reactions
Oxidation = combination of an element with oxygen to produce an oxide.
Reduction = loss of oxygen from a compound.
Acids, Bases, & Salts
Acids taste sour, will change the color of an acid-base indicator, and can be strong
or weak electrolytes in aqueous solutions.
Vinegar (acetic acid)
