Directions:
View the Power Point study guide with the same title as this handout. Record all your answers
below.

1. In the periodic table, each row is called a _______________________________ .

2. The elements in each ____________________________ have the same number of

___________________________________________________ .

3. Each column in the periodic table is called a _________________ or _________________ .

4. Each of the elements in the same ________________________ have the same number of

__________________________ in their outer shells.

5. The electrons in the outer shell are called ________________________ electrons.

6. The ______________________ number equals the ______________________ of

Bohr Model Notes: The Basics

1. Find your ______________________________ on the periodic table.
2. Determine the number of ______________________________ — it is the same

as the atomic number.
3. This is how many electrons you will __________________________.
4. Find out which _____________________________________ your element is in.

This will tell you how many energy levels, or _____________________________
you will need to draw.
5. Draw your electrons in a _________________________ clock-wise pattern,
always starting at the _____________________________________.
