Electronic Distribution (with Summary)

WATCH THE VIDEO OF THE COMPLETE ACTIVITY

⚠️ This material is an adapted Chemistry activity designed to teach Electron Configuration in a visual, progressive, and accessible way.

Number of questions in the activity:

5 adapted questions + introductory summary + complete answer key, distributed across 3 activity pages.

The activity follows a progression that begins with locating electrons in the electron cloud, moves on to basic concepts of electron configuration, explores the maximum number of electrons in the first electron shells, and progresses to the visual identification of a specific shell and the sequence K, L, M, N, O, P, and Q.

Target audience:

The material can be used in middle school and high school, depending on students’ curriculum adaptation needs. The file presents Electron Configuration as a learning objective within the thematic unit Matter and Energy.

It may especially support students with mild to moderate Intellectual Disabilities, Autism Spectrum Disorder (ASD), ADHD, Down Syndrome, reading and comprehension difficulties, and difficulties learning Chemistry.

It is particularly suitable for students who find the abstract nature of atomic structure challenging, as it uses color-coded representations of electron shells, spatial organization, and repetition of essential concepts to make electron configuration more concrete.

Content covered:

The summary explains that electrons are located around the nucleus, in the electron cloud, and are organized into electron shells or energy levels. It also presents the shells K, L, M, N, O, P, and Q and the maximum capacities covered in the material: K = up to 2 electrons, L = up to 8 electrons, and M = up to 18 electrons.

Students also learn that electrons first occupy the shells closest to the nucleus, which have lower energy, before occupying shells farther away.

Important information for teachers:

Before beginning the questions, students are provided with a visual summary accompanied by an atomic model. This page introduces the electron cloud, electron shells, their corresponding letters, and the maximum numbers of electrons in the K, L, and M shells. This allows students to refer back to the essential information while completing the activity, reducing the need for immediate memorization.

In the first question, students observe a model of an atom and identify where electrons are located. Among the options, they must recognize that electrons are found in the electron cloud, around the nucleus.

In the second question, students classify statements about electron configuration as true or false. They review information such as the maximum number of electrons in the first shells, the order in which shells are occupied, and the possibility of an atom having electrons in more than one shell.

In the third question, students match the 1st, 2nd, and 3rd shells with their respective maximum capacities: up to 2, up to 8, and up to 18 electrons. This reinforces the relationship between each shell and its electron capacity using information provided for selection.

In the fourth question, students observe a diagram with colored concentric shells, identified by the letters K, L, M, N, and O, and determine which shell contains the indicated electron.

Finally, in the fifth question, students identify the correct order of the electron shells, reinforcing the sequence K, L, M, N, O, P, and Q introduced in the initial summary.

Key features:
