This companion handout is designed to pair with Crash Course Chemistry: Atomic Hook Ups. A QR code to the Youtube video is included. The handout helps students actively engage with the video while building a deeper understanding of periodic trends. On the front, students complete guided notes and questions aligned with the video to reinforce key concepts. On the back, four blank periodic tables allow students to sketch the gradients for: - Atomic Radius - Electron Affinity - Ionization Energy -
