Valence Electron Lesson Plan

Instructor: Adrianne Baron

Adrianne has taught high school and college biology and has a master's degree in cancer biology.

Each element in our world has its own unique electron configuration and number of valence of electrons. Your students will gain a solid understanding of valence electrons as they watch a video, create electron configuration books, and take a quiz.

Learning Objectives

At the completion of this lesson, students will be able to:

  • Define valence electrons
  • Identify the number of valence electrons in various chemicals
  • Draw electron configurations

Length

1.5 - 2 hours

Curriculum Standards

  • CCSS.ELA-LITERACY.RST.9-10.1

Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions.

  • CCSS.ELA-LITERACY.RST.9-10.4

Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9-10 texts and topics.

CCSS.ELA-LITERACY.RST.9-10.7

Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.

Materials

  • Copies of the periodic table
  • Copies of the lesson quiz
  • Printer paper
  • Colored pencils
  • Computer with projector
  • Scissors

Instructions

  • Start the lesson by telling your students that they are going to learn more about the electrons in atoms, particularly the valence electrons as they watch Valence Electrons: Definition, Configuration & Example.
  • Play the video for your students and pause it periodically for discussions.
  • Pause the video the first time at 2:46, then ask and discuss the following:
    • What are valence electrons?
    • How many electrons can shell 1 hold?
    • Which orbitals exist in shell 1?
    • How many electrons can shell 2 hold?
    • Which orbitals exist in shell 2?
    • How many electrons can shell 3 hold?
    • Which orbitals exist in shell 3?
  • Continue playing the video, pausing it again at 5:36 to ask and discuss following:
    • What is an electron configuration?
    • What is spdf notation?
    • What tells you the number of electrons in an atom?
  • Continue playing the video through 8:01, then pause it to ask and discuss:
    • What is noble gas configuration?
    • What is a noble gas?
    • How do you determine how many electrons to write in the configuration when using noble gas configuration?
  • Play the rest of the video for your students and answer any questions.
