Grade 9s began the second chemistry chapter which focuses on the periodic table and atomic model theories. Today we reviewed current student understanding of key concepts. We then learned about the 3 main sections of the periodic table metals, metalloids, and non-metals. Students have been challenged to memorise the names and symbols of the first 20 elements by January 7th.
