Elements that are in the same group on the periodic table share similar chemical properties. This happens because they have the same setup of valence electrons, which are the outermost electrons in an atom.
But this idea can be hard for students to understand for a few reasons:
Abstract Thinking: Valence electrons are tiny and cannot be seen. To get this concept, students need to understand how atoms are built.
Patterns: It can be tricky for students to find similarities when there are obvious differences.
To help students understand better, teachers can try these strategies:
Use pictures or diagrams to show how electron configurations work.
Plan hands-on activities that help students see the similarities between different groups of elements.
