Learning Objectives

5.1.2.3 Metals and non-metals

Content	Key opportunities for skills development
$Elements that react to form positive ions are metals. Elements that do not form positive ions are non-metals. The majority of elements are metals. Metals are found to the left and towards the bottom of the periodic table. Non-metals are found towards the right and top of the periodic table. Students should be able to: explain the differences between metals and non-metals on the basis of their characteristic physical and chemical properties. This links to Group 0 (page 74), Group 1 (page 74), Group 7 (page 75) and Bonding, structure and the properties of matter (page 75) explain how the atomic structure of metals and non-metals relates to their position in the periodic table explain how the reactions of elements are related to the arrangement of electrons in their atoms and hence to their atomic number.$
