Lesson 4 – Periodic Table Learning Objectives: 1.Describe the history of the development of the modern periodic table. 2.Explain how the periodic table is organised. 3.Locate on the periodic table and explain the properties of metals and non-metals. 4.Analyse the properties of Group 0, Group 1, and Group 7 elements. 5.Link the arrangement of groups on the periodic table to electron configuration and chemical properties.
