3. Chemistry Battleship
Groups or Families: Vertical Columns of the Periodic Table
Period or Series: Horizontal Rows of the Periodic table
Example: Group 9, Period 5
Example: Family 12, Series 4

5. Valence Electrons
Number of electrons in the outermost shell (orbital)

6. Lewis Structures Find your element on the periodic table.
Determine the number of valence electrons.
This is how many electrons you will draw.

7. Lewis Structures 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.

8. Groups - Review Group 8 = 8 electrons Group 1 = 1 electron
Except for He, it has 2 electrons
Group 2 = 2 electrons
Each column is called a “group”
3, 4, 5, 6, 7
Each element in a group has the same number of electrons in their outer orbital, also known as “shells”.
The electrons in the outer shell are called “valence electrons”

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

10. C Lewis Structures Check your work.
Using your periodic table, check that Carbon is in the 4th group.
You should have 4 total electrons, or dots, drawn in for Carbon. C

11. C Lewis Structures On your worksheet, try these elements on your own:P Ca Ar Cl Al C

18. Bohr Model Drawings
Identify the number of Protons, Neutrons, and Electrons in an element.
Write the number of Protons and Neutrons in the center of the nucleus.
Draw the number of electrons in each of the orbitals.
1st Orbital: 2 electrons
2nd Orbital: 8 electrons
3rd Orbital: 18 electrons
4th Orbital: 32 electrons
