2 The Periodic Table BY: BRIANNA SHIELDS

3 DO NOW 1. What element has 7 protons? 2. How many neutrons does Hydrogen have? 3. How many electrons does Neon have?

4 GOAL To construct Bohr models To use the periodic table and become familiar with its elements

5 Review: Fill in the table ParticleChargeMassLocationChart 1. Proton 2. Electron 3. Neutron

6 Review: Atoms How many protons, neutrons and electrons?

7 How many p, n, e?

11 Steps to creating a Bohr Model 1. Create a key: #p, #n, # e 2. Draw the nucleus w/ several rings 3. Put P and N in nucleus 4. Put E into orbits from inside to outside 1. 1st level holds 2 electrons 2. 2nd holds rd holds th holds 32 maximum numbers of e’s that each level can hold

12 Lithium 3P 4N KEY #p= 3 #n= 4 #e= 3

13 Bohr Model Example

15

16 Make a Bohr model of Magnesium. Don’t forget to make a key.

17 Magnesium 12P 12N KEY #p= 12 #n= 12 #e= 12

18 Draw the following Bohr Models: Random students will be chosen to draw theirs on the board (don’t forget to make a key) Neon Hydrogen Potassium

19 Periodic Table Websites ACS Periodic Table

20 The Periodic Table- Video What is the name for the element group in the first column of the periodic table? What is the name for the element group in the last column of the periodic table?

21 The Periodic Table- Video

22 Trends in the Periodic Table ACS Periodic Table Chemistry: WebElements Periodic Table A Periodic Table of the Elements at Los Alamo... A Periodic Table of the Elements at Los Alamo... Chemical Elements.com - An Interactive Period... Chemical Elements.com - An Interactive Period...

23 The Periodic Table You should be coloring in and labeling your periodic table, as we take notes

24 Periodic Table Trends 1. Atomic number increases left to right, top to bottom

25 Periodic Table Trends 2. Groups / Families = Vertical Columns Gp 1= Alkali metals Gp 2= Alkaline earth metals Gp 17= halogens Gp 18= noble gases

26

27 Group 1= Alkali Metals

28 Group 2= Alkaline Earth Metals

29 Gp 17= Halogens

30 Gp 18= Noble Gases

31 Periodic Table Trends 3. Periods = horizontal rows

32 Periodic Table Trends 4. Metalloids= along stair step line (metal and non-metal characteristics)

33 Periodic Table Trends 5. Metals= everything to left of stair step line

34 Periodic Table Trends 5. Metals= everything to left of stair step line A. Usually have high melting points. B. Shiny when cut. C. Mostly tough, strong, malleable and ductile. D. Good conductors of heat. E. Good conductors of electricity. F. Form alloys

35 Periodic Table Trends 6. Non-metals = everything to right of stair step line (most common)

36 Periodic Table Trends 6. Non- Metals A. dull B. poor conductors C. brittle D. lower densities E. lower melting points F. some are solids, some liquids, and some gases

37 Periodic Table Trends 7. Transition elements- elements in gps 3-12 with unusual properties

38 Describe the locations of the elements Ex: Neon is a non-metal located in period 2, gp 18 (noble gases) Sodium A metal located in period 3, gp 1, the Nickel A transition metal located in period 4, gp 10 Fluorine A non-metal in period 2, grp 17 (halogens)

39 Describe the locations of the elements Ex: Neon is a non-metal located in period 2, gp 18 (noble gases) Aluminum A metalloid in period 3, group 13 Hydrogen A non-metal located in period 1, gp 1

40 How many p, e and n? K Chemical Symbol Atomic Number Atomic Mass

41 How many p, e and n? Cu

42 Review: Bohr Models Make a Bohr Model of Lithium

43 Lithium 3P 4N KEY #p= 3 #n= 4 #e= 3

44 Review: Bohr Models Make a Bohr Model of Silicon

45 Silicon 14P 14N KEY #p= 14 #n= 14 #e= 14

46 Do you know your elements yet?? Be I Sn Ag C

47 Do you know your elements yet?? He U Ba Mg K

48 Do you know your elements yet?? Ne P Cl Pt Au

49 Do you know your elements yet?? Hg Rn Co Mn Cu

50 Do you know your elements yet?? As Zn F Na Si P
