The Structure of the Atom, Chemical Bonding Lesson Plan
Content
Understand and list the properties of protons, neutrons, and
electrons.
Key Words: atom, nucleus, neutron, electron, proton, atomic
number, mass number
-Ionic/ covalent bonds
Goals / Aims of The Lesson Plan
1. Students will understand the core parts of an atom.
2. Students will know the difference between an element and
compound.
3. Students will be able to differentiate between elements of
atoms based on their atomic composition.
4. To draw 'dot and cross' diagrams
5. To identify ionic or covalent compounds.
Objectives
1. Summarize Rutherford discovery
2. Explain the differences between isotopes and physical
activity that it demonstrates.
3. Solve problems involving mass in grams
4. To list properties of ionic compounds
5. To list properties of covalent compounds.
Materials and Aids

Graphing calculator, textbook, Periodic Table
Procedure
A. Introduction1.We will discuss Cathode Rays and electrons; Gold foil
experiment
2.Composition of Nucleus
3. Isotopes - How are isotopes formed and how stable are
they?
4. Demo Time: A synthesis reaction between Hydrogen and
Oxygen
5. A combustion reaction showing how water breaks apart to
make 2H + O
B. Development1. How do elements stick together to form a compound?
2. How do compounds stick together to form different
compounds?
3. Introduce concept of bonds
4. Students understand types of reactions.
5. Students gain necessary knowledge behind chemistry.
C. Practice1. Have students work on a "What happens during chemical
reactions" worksheet. These should include the following
reaction types. Redox,Synthetic,combustion, and simple

reactions
2.Sample problem B page 84 3.Sample problem C page 85
D. Independent Practice1. Students will walk between stations and determine if what is
presented is an element or compound.
2. They will also determine, if they answer "element", if they are
presented with a unique isotope of the element.
3. If students determine the substance presented is a
compound, they must determine the type of bond present in the
compound. They should be given reference to a periodic table
at all times.
E. Accommodations (Differentiated Instruction)1.Students given several problems and teacher to move around
to see who has got problem.
F. Checking for understanding1. Q & A and a short quiz.
2. If less than 80 percent of students pass, more in class
practice.
3. Reviewing what was learned in class.
G. Closure1. Reminder of homework
2. Reminder of the next day's lesson and quiz.
