Monday November 3 rd, 2014 Entry Task/Warm-Up Please take your notebook and quietly review your notes! Due Today: Nothing Due Today!! Homework: 1.Matter Graphic Organizer due Tuesday 11/4/2014 for 20 Points FIVE FACTS PER BUBBLE!!! Schedule: Quiz: Periodic Table and History of Atom Objective: I can identify and construct Bohr and Lewis Structures

Tuesday November 4 th, 2014 Entry Task/Warm-Up Please take your notebook and your homework! Due Today: Matter Graphic Organizer!! Homework: 1. Matter Graphic Organizer due Tuesday 11/4/2014 for 20 Points Schedule: Notes: How to construct a Bohr Model of an Atom Objective: I can identify and construct Bohr and Lewis Structures

Bohr Diagrams Review 1)Draw a nucleus with the element symbol inside. 2)Carbon is in the 2 nd period, so it has two energy levels, or shells. 3)Draw the shells around the nucleus. C C

Bohr Diagrams Review 1)Add the electrons. 2)Carbon has 6 electrons. 3)The first shell can only hold 2 electrons. C C

Bohr Structure 1)Since you have 2 electrons already drawn, you need to add 4 more. 2)These go in the 2 nd shell. 3)Add one at a time - starting on the right side and going counter clock-wise. C C

Bohr Diagrams Try the following elements on your own: a)H b)He c)O - 8 electrons d)Al e)Ne f)K O O

Bohr Diagrams Try the following elements on your own: a)H b)He c)O d)Al - 13 electrons e)Ne f)K Al

Bohr Diagrams Try the following elements on your own: a)H b)He c)O - 8 electrons d)Al e)Ne f)K O O

1)Check your work. 2)You should have 6 total electrons for Carbon. 3)Only two electrons can fit in the 1 st shell. 4)The 2 nd shell can hold up to 8 electrons. 5)The 3 rd shell can hold 18, but the elements in the first few periods only use 8 electrons. C C Bohr Diagrams Review Complete Atomic Basic Worksheet

Bohr Diagrams Try the following elements on your own: a)H b)He c)O d)Al - 13 electrons e)Ne f)K Al

Tuesday, October 29 th, 2013 Entry Task/Warm-Up Please take your notebook and your homework Due Today: Bohr Structure Practice Homework: 1.Lewis Structure Practice Wed/Thurs 10/30-10/31 for 27 Points Schedule: Notes: Lewis Structures Objective: I can differentiate between chemical and physical properties

Lewis Structures Review Find out which group (column) your element is in. This will tell you the number of valence electrons your element has. You will only draw the valence electrons. www.chem4kids.com

Lewis Structures Review 1)Write the element symbol. 2)Carbon is in the 4 th group, so it has 4 valence electrons. 3)Starting at the right, draw 4 electrons, or dots, counter- clockwise around the element symbol.

Lewis Structures Review 1)Check your work. 2)Using your periodic table, check that Carbon is in the 4 th group. 3)You should have 4 total electrons, or dots, drawn in for Carbon. Complete Lewis Structure Notes Worksheet and Atomic Basic Worksheet SHOW FOR A STAMP WHEN DONE!

Lewis Structures Homework Assignment On a sheet of paper draw Lewis Structures for the following elements: Hydrogen, Barium, Silicon, Neon, Oxygen, Sulfur, Iodine, Magnesium, Aluminum, Potassium, Bromine, Arsenic, Fluorine, Sodium, Calcium, Strontium, Rubidium, Cesium, Xenon, Indium, Tin, Selenium, Tellurium. Draw Bohr Structures for the following elements: Boron, Sulfur, Hydrogen and Magnesium

Wed/Thurs 10/30-10/31/2013 Entry Task/Warm-Up Please take your notebook and your homework Due Today: Lewis Structure Practice Homework: 1.Physical vs. Chemical Properties Worksheet due Friday 11/1/2013 for 15 Points Schedule: Notes: Physical and Chemical Changes Objective: I can differentiate between chemical and physical properties

Atomic Basics Worksheet!! You will have 30 minutes in class to complete this assignment. It will be TURNED IN FOR A GRADE, not on your stamp sheet. When you are finished, bring it up to Ms. Andrews’ desk and find something quietly to do for the remainder of the time This assignment is worth 25 points before the end of the hour, if it is not finished, TURN IT IN TORMORROW FOR LATE CREDIT!!
