Understanding Valence Electrons and Bonding

This week's lesson for grade eight covers bonding and the periodic table. The teacher reviews the remaining objectives from the previous lesson, focusing on halogens and noble gases. The new lesson introduces valence electrons and their role in bonding, including how to draw and interpret electron dot diagrams. Students will engage with interactive periodic tables, live worksheets, articles, and videos to deepen their understanding. The lesson concludes with a reminder of available support and resources.
