About This Chapter
Below is a sample breakdown of the Periodic Table chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||The periodic table||Elements and their physical properties, groups, periods|
|Tuesday||Electrons||Electron shell, valence electron, noble gases, energy levels, atoms|
|Wednesday||Groups and periods||Atomic radii, ionic radii, ionization energy, electronegativity|
|Thursday||Relationships among elements||Boiling point, metallic character, diagonal relationships|
|Friday||Specialized elements and their characteristics||Transition metals, main group elements|
1. The Periodic Table: Properties of Groups and Periods
In the late 1800s, Russian chemist Dmitri Mendeleev created the periodic table by organizing elements by their atomic weight in increasing order. Learn about Mendeleev, discover how the elements on the periodic table are organized, and explore the properties of periods and groups.
2. Valence Electrons and Energy Levels of Atoms of Elements
Valence electrons are the outer electrons in an atom that participate in chemical reactions and determine chemical changes to atoms and molecules. Learn about valence electrons, the significance of orbital location, and how to represent the number of valence electrons in a Lewis dot diagram.
3. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table
The size of an atom is determined by the distance of the valence electrons from the nucleus. Learn about atomic and ionic radii trends among groups on the periodic table, and how to predict the relative size of an atom based on where it is located on the periodic table.
4. Ionization Energy: Trends Among Groups and Periods of the Periodic Table
Ionization energy is the amount of energy needed to remove an electron from an atom. On the periodic table, as atoms increase in size, the amount of energy needed to remove an electron decreases. Learn about ionization energy and how to identify ionization trends on the periodic table.
5. Electronegativity: Trends Among Groups and Periods of the Periodic Table
Electronegativity measures an atom's tendency to attract a bonding pair of electrons. Explore electronegativity and its trends among groups and periods in the periodic table and discover why some elements are more electronegative than others.
6. The Diagonal Relationship, Metallic Character, and Boiling Point
The 118 known elements currently on the periodic table are organized by increasing atomic weight, but there are also several trends or relationships among and between the elements. Learn about three trends on the periodic table (diagonal relationship, metallic character, and boiling point) and discover why metals are excellent conductors of electricity.
7. Transition Metals vs. Main Group Elements: Properties and Differences
On the periodic table, main group elements are found in groups 1, 2, and 13-18, while transition metals are found in groups 3-12. Learn about the properties of transition metals, main group elements, and how to compare and contrast the characteristics of transition metals with main group elements.
