1 Periodic Table of Elements Help By: James Butler (Chem.11) See his original on the student section site of the chemistry site

2 What is it? The periodic table is an arrangement of all the elements to show their similarities The periodic table is an arrangement of all the elements to show their similarities Each element is set up with its’: Each element is set up with its’: Atomic number Element symbol Average atomic mass

3 When was it discovered? The first periodic table was discovered in 1869, by Dmitry I. Mendeleyev. “Father of periodic table” The first periodic table was discovered in 1869, by Dmitry I. Mendeleyev. “Father of periodic table”

4 A Brief history of the periodic table! http://periodictable.com/pages/A AE_History.html

5 Basic Periodic Table!

6 Individual Element!

7 Quick Facts The elements are placed in boxes in the periodic table. A symbol is used to represent the full name of an element. For example, H represents hydrogen; O represents oxygen, and Al represents aluminum. The elements are placed in boxes in the periodic table. A symbol is used to represent the full name of an element. For example, H represents hydrogen; O represents oxygen, and Al represents aluminum. Sometimes the Latin name for an element is used as the basis for its symbol, for instance K represents potassium (kalium in Latin). Sometimes the Latin name for an element is used as the basis for its symbol, for instance K represents potassium (kalium in Latin).

8 You guide to periodic table success! On the next test, and maybe on the exam, you will have to be able to draw and label the periodic table.

9 Step 1: Know the general shape of the periodic table, to element 86.

10 Atomic numbers flow from 1 to 86. You will see this already done for you but you will need to know how to do this. This was done on the yellow sheet to save time.

11 Step 2: Know the general trend for the number of blocks in each period. Period 1 – 2 elements Period 1 – 2 elements Period 2 – 8 elements/blocks Period 2 – 8 elements/blocks Period 3 – 8 elements/blocks Period 3 – 8 elements/blocks Period 4 – 18 elements/blocks Period 4 – 18 elements/blocks Period 5 – 18 elements/blocks Period 5 – 18 elements/blocks Period 6 – 18 elements/blocks Period 6 – 18 elements/blocks

12 Step 3: Note the numbering change for Period 6. (55 56 ---- 71)

13 Step 4: Know how to label all the groups Remember there are A and B group elements. 1A, 2A, 3A, 4A, 5A, 6A, 7A, 0, (The top) 3B, 4B, 5B, 6B, 7B, 8B(3 isles), 1B, 2B (Transition metals)

14 Step 5: Draw in the metalloid staircase; from Boron to Astatine. Draw in the metalloid staircase; from Boron to Astatine.

15 Step 6: Label the following groups according to their names Group 1A- alkali metals Group 2A- alkaline metals Group 7A- Halogens Group 0- noble gases, inert gases All A groups- representative elements All B groups- transition metals All metals, non-metals, and metalloids

16 Step 7: Label the following series of elements on a periodic table. Atomic # 57 to 70 – Lanthanides Atomic # 89 to 102- actinides Both of the above series are labelled as the Inner transition metals

17 Step 8: Know ionic charges associated with each group. (Chapter 5)

18 Divisions of the periodic table Alkali Alkaline Transition metals Non Metals Halogens Nobel Gases Lanthanide Actinides Hydrogen These are the basic divisions of the Periodic table

19 Basics of periodic table construction! Arranged in rows and columns based on their similarities in properties. Groups – vertical column of elements. Groups – vertical column of elements. Periods- horizontal column of elements. Periods- horizontal column of elements.

20 There are 2 types of group elements: Group A elements – representative elements, called this because they display the entire range of chemical properties, has metals and non-metals. Group B elements – The transition elements and inner transition elements. (Remember their location from construction)

21 Metals: Located to the left. Note: Hydrogen (a gas) is the only non-metal on the left side of the periodic table. Non-metals: Located to the right. Note the division between the 2 types is the staircase; these elements are called the metalloids.

22 We must recognize Metals and Non-metals just by looking at the periodic table. We can do this based on their position in the table. Believe me, you must be able to do this to do the course. The easiest way to memorize all the metals and non-metals is to just know the location of the non-metals, the rest are all metals. 3A4A5A6A7A CNOF Last group are noble gases, CNOF Last group are noble gases, PSCl They are non-metals but PSCl They are non-metals but SeBr are unreactive. Therefore, SeBr are unreactive. Therefore, I no need to list them. I no need to list them.

23 Properties of Metals: Properties of Non-metals lustre (Shinny) conductors of heat/electricity most solid at room temp. ductile – drawn into a wire malleable – hammered into sheets non-loustrous Non-conductors of heat/electricity Solid, liquid or gas at room form brittle solids Properties of Metalloids: Properties of Metalloids: displays properties of metals and non-metals. Metalloids are a problem, they can be classed as both, we rarely use them in this class.

24 Important groups: Important groups: Group 7A – Halogens: they are highly reactive. Group 7A – Halogens: they are highly reactive. Group 0 – noble gases Group 0 – noble gases Group 1A – akali metals Group 1A – akali metals Group 2A - Alkaline earth metals Group 2A - Alkaline earth metals All “B” groups – Transition metals All “B” groups – Transition metals All “A” groups – Representative elements (Wide range of properties) All “A” groups – Representative elements (Wide range of properties)

25 Class Activity! Referring to a periodic table, classify each of the following as: Representative elementInner Transition element Transition elementNoble gas Note: If it is a representative element, indicate which group and whether it is a metal, non-metal or a metalloid Tl – 81h) Se - 34 Eu – 63I) As - 33 Xe – 54j) Mo - 42 Hf – 72K) Rn - 86 Ru – 44l) Ta - 73 Am – 95m) Bi - 83 B – 5n) In - 49
