The Periodic Table BY: BRIANNA SHIELDS
DO NOW 1. What element has 7 protons? 2. How many neutrons does Hydrogen have? 3. How many electrons does Neon have?
GOAL To construct Bohr models To use the periodic table and become familiar with its elements
Review: Fill in the table ParticleChargeMassLocationChart 1. Proton 2. Electron 3. Neutron
Review: Atoms How many protons, neutrons and electrons?
How many p, n, e?
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
Lithium 3P 4N KEY #p= 3 #n= 4 #e= 3
Bohr Model Example
Make a Bohr model of Magnesium. Don’t forget to make a key.
Magnesium 12P 12N KEY #p= 12 #n= 12 #e= 12
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

The Periodic Table You should be coloring in and labeling your periodic table, as we take notes
Periodic Table Trends 1. Atomic number increases left to right, top to bottom
Periodic Table Trends 2. Groups / Families = Vertical Columns Gp 1= Alkali metals Gp 2= Alkaline earth metals Gp 17= halogens Gp 18= noble gases
Group 1= Alkali Metals
Group 2= Alkaline Earth Metals
Gp 17= Halogens
Gp 18= Noble Gases
Periodic Table Trends 3. Periods = horizontal rows
Periodic Table Trends 4. Metalloids= along stair step line (metal and non-metal characteristics)
Periodic Table Trends 5. Metals= everything to left of stair step line
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
Periodic Table Trends 6. Non-metals = everything to right of stair step line (most common)
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
Periodic Table Trends 7. Transition elements- elements in gps 3-12 with unusual properties
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)
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
How many p, e and n? K Chemical Symbol Atomic Number Atomic Mass
How many p, e and n? Cu
Review: Bohr Models Make a Bohr Model of Lithium
Lithium 3P 4N KEY #p= 3 #n= 4 #e= 3
Review: Bohr Models Make a Bohr Model of Silicon
Silicon 14P 14N KEY #p= 14 #n= 14 #e= 14
