1. Atoms, Elements and compounds Lesson 2: Getting Sorted

2. Get started... 1.What is an element? 2.What is a molecule? 3.What do these symbols stand for? Fe Au Ag Na Homework: Research the history of the periodic table. Who developed it? Was it always the same way as we know it today? Due Wed 16 th November

3. Divide the pictures into 2 groups.... How did you decide how to group your cards?

4. Learning Objectives 1.To know the Difference in metals and non- metals 2.To know how the periodic table is divided into metal and non- metals Learning Outcomes 1.To be able to describe the properties of metals and non- metals 2.To be able to show on the periodic table where metals are and where non- metals are

5. Can you think of some of the properties of each one?? Properties of metals Properties of non- metals

6. Arranging elements

7. antimony (Sb) Is this element a or a ? H Li Na K Rb Cs Fr Be ScTi Mg VCrMnFeCoNiCuZnGaGeSeBrCaKr YZrNbMoTcRuPdAgCdInSnSbSrTeRh BaHfTaWReOsIrAuHgTlPbBiPoLaAtPt RaRfDbSgBhHsMt??Ac? AlP NO SCl FNe Ar Rn I Si Xe He BC As Fe MgSP S P Cu metalnon-metal IISb Hard to say! Sb Metal or non-metal? iodine (I) iron (Fe) copper (Cu) phosphorus (P) sulfur (S) magnesium (Mg)

8. Metals and non-metals in the periodic table The periodic table is a list of all the known elements which are arranged according to the similarities in their properties. Non-metals are mostly on the right. Metals are on the left and in the centre. What type of elements are between metals and non-metals? Xe

9. Types of elements in the periodic table

10. Metal, non-metal or metalloid? H Li Na K Rb Cs Fr Be ScTi Mg VCrMnFeCoNiCuZnGaGeSeBrCaKr YZrNbMoTcRuPdAgCdInSnSbSrTeRh BaHfTaWReOsIrAuHgTlPbBiPoLaAtPt RaRfDbSgBhHsMt??Ac? AlP NO SCl FNe Ar Rn I Si Xe He BC As silicon (Si) metalloid francium (Fr) metal scandium (Sc) metal krypton (Kr) non-metal cobalt (Co) metal What are metalloids? Which side are the non- metals on? Which side are the metals on? Metalloids sometimes behave like metals and sometimes like non-metals. Metals are on the left and in the centre. Non-metals are mostly on the right.
