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

222222

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
