Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson plan

Lesson Plan: Electron Configuration

Topic

Electron Configuration

Objectives

Understand the concept of electron configuration and its significance in chemistry.
Identify the correct electron configuration for the first 20 elements of the periodic table.
Apply the Aufbau principle, Hund's rule, and Pauli exclusion principle in determining electron configurations.

Materials

Whiteboard and markers
Projector and slides on electron configuration
Handouts of the periodic table
Electron configuration practice worksheets
Access to online simulations (if possible)

Grade/Age Group

Year/Grade 10 (15-16 years old)

Subject

Chemistry

Class Size

20 students

National Curriculum Alignment

This lesson aligns with the U.S. Next Generation Science Standards (NGSS) for High School Chemistry.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction	5	Brief overview of what electron configuration is and why it matters in chemistry. Connect to prior knowledge of atomic structure.
2	The Aufbau Principle	5	Explain the Aufbau principle and how it guides the order of electron filling in orbitals. Use visual aids on the projector.
3	Hund's Rule & Pauli Exclusion	5	Introduce Hund's rule and the Pauli exclusion principle through examples. Use diagrams to illustrate these concepts.
4	Demonstration	5	Demonstrate electron configurations for the first 10 elements using the periodic table, writing configurations on the whiteboard.
5	Guided Practice	5	Work through electron configurations for elements 11-20 as a class, encouraging participation and discussion.
6	Independent Practice	5	Distribute practice worksheets for students to complete individually, applying concepts learned. Encourage silent work to reinforce learning.
7	Check for Understanding	3	Use a quick formative assessment (exit ticket) where students write one electron configuration they learned. Collect for review.
8	Homework Assignment	2	Assign homework where students will complete additional electron configuration practice and review the concepts discussed in class.

Homework Check

Homework will be checked through a quick review of submitted worksheets without requiring students to present their work in front of the class. Feedback will be provided through written comments.

Assessment

Formative assessment through observation during practice.
Check for understanding via exit tickets.
Review of homework for completion and accuracy.

Additional Notes

Encourage a collaborative environment where students can ask questions and support each other while working independently. Be available to provide support during guided and independent practice time.
