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 2nd period, so it has two energy levels, or shells.
3) Draw the shells around the nucleus.
C
Bohr Diagrams Review
1) Add the electrons.2) Carbon has 6
electrons.3) The first shell can only
hold 2 electrons.C
Bohr Structure
1) Since you have 2 electrons already drawn, you need to add 4 more.
2) These go in the 2nd shell.
3) Add one at a time -starting on the right side and going counter clock-wise.

Bohr Diagrams
Try the following elements on your own:
a) Hb) Hec) O - 8 electronsd) Ale) Nef) K
O
1) Check your work.2) You should have 6 total
electrons for Carbon.3) Only two electrons can
fit in the 1st shell.4) The 2nd shell can hold
up to 8 electrons.5) The 3rd shell can hold
18, but the elements in the first few periods only use 8 electrons.

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.

Lewis Structures Review
1) Write the element symbol.
2) Carbon is in the 4th group, so it has 4 valence electrons.
3) Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol.
C
Lewis Structures Review
1) Check your work.2) Using your periodic
table, check that Carbon is in the 4th group.
3) You should have 4 total electrons, or dots, drawn in for Carbon.

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!!
