The Structure of the Atom, Chemical Bonding Lesson Plan


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.


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


A. Introduction-

1.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. Development-

1. 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. Practice-

1. 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 Practice-

1. 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 understanding-

1. 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. Closure-

1. Reminder of homework
2. Reminder of the next day's lesson and quiz.
