 TO KNOW the meaning of terms periodic table, group, period, metal, non-metal, gas, transition metal,  TO BE ABLE to identify the terms on the periodic table.  TO begin to UNDERSTAND why the periodic table is structured the way it is. Objectives

 Glue in Periodic Table in your workbook.  Lets start…………………. Activity

Variety  There are millions of substances in the world.  All these substances are made from about 100 different building blocks called elements.  These elements take a huge variety of forms: to unreactive metals like gold To the air we breathe From poison gases like chlorine From reactive metals like sodium

Properties of Elements properties In science the word properties means, what the substance is like. For example, here are some properties of sodium:  Metallic  Highly reactive  Solid but melts easily  Low density (light) It would be really useful to be able to predict properties of elements instead of having to remember them!

The Arrangement of the table is not to make it look pretty. It is done for a purpose. In Chemistry this year, you will gain a better understanding of why it is arranged like this.

Groups – columns of elements groups. Downward columns are called groups.

Periods – rows of elements periods Rows of elements are called periods. H He 1 LiBeNOFNeBC 2NaMgAlPSClArSi3KScTiVCrMnFeCoNiCuZnGaGeSeBrCaKrAs4RbYZrNbMoTcRuPdAgCdInSnSbSrTeRhIXe5CsBaHfTaWReOsIrAuHgTlPbBiPoLaAtPtRn6FrRaRfDbSgBhHsMt??Ac?7 Period Number

Missing elements! Below the chemical symbol have been replaced by atomic numbers. You will see some are missing! Two further series of elements should go here but are only shown on some Periodic Tables. They are called the lanthanides and actinides.

Patterns 1. Metals and Non-metals Metals are on the left and centre. Non-metals are mostly on the right In between are metalloids. These are like metals in some ways and like no- metals in others.

Patterns 1. Metals and Non-metals

Say whether these elements are metals, non- metals or metalloids.

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

Physical state means – is it a solid, liquid or gas. There are only 2 liquid elements. Notice how most of the gases are on the far right. Physical State

Say whether these elements are solids, liquids or gases. 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 Krypton (Kr) Gas Kr Niobium (Nb) Solid Nb Barium (Ba) Ba Solid Nitrogen (N) N Gas Bromine (Br) Br Liquid

Patterns 2. Reactivity of Metals  As a general, but not perfect, rule: the further to the left and the further down the table - the more reactive the metal is. More Reactive

Potassium (K) or Lithium (Li) Which metal is most reactive? H Li Na K Rb Cs Fr Be ScTi Mg VCrMnFeCoNiCuZnGaGeCa YZrNbMoTcRuPdAgCdInSnSbSrRh BaHfTaWReOsIrAuHgTlPbBiPoLaPt RaRfDbSgBhHsMt??Ac? Al K Calcium (Ca) or Magnesium (Mg) Ca Calcium (Ca) or Iron (Fe) Ca Copper (Cu) or Barium (Ba) Ba

Patterns 3. Reactivity of Non-Metals This is more complicated. At the very end of the periodic table is the most unreactive group of elements in the table. Apart from that – the further up and the further right – the more reactive the non-metal. More reactive

Neon (Ne) or Iodine (I) Which non-metal is most reactive? SeBrKr Te At P N O S Cl F Ne Ar Rn I Si Xe He BC As I Oxygen (O) or Silicon (Si) O Fluorine (F) or Chlorine (Cl) F Carbon (C) or Oxygen (O) O
