Lewis Dot Diagrams

Since atoms are only concerned with having a full outer/valence shell. It is sometimes more convenient to look at the valence shell. Electrons in the valence shell are called valence electrons.

Lewis Dot Diagram A Lewis Dot Diagram is a diagram of the atom where only the valence electrons are drawn. Valence electrons are represented by dots. The nucleus of the atom is represented by the atom’s symbol only.

Lewis Dot Diagrams Since a full valence shell normally consists of 8 electrons, Lewis dot diagrams are drawn with two dots on the top, bottom, left and right. We only draw electrons for the outer shell.

Sulfur has 16 electrons. K = 2 L= 8 M = 6 (Valence shell) Draw the Lewis Dot Diagram S

The Periodic Table We’ll be talking about this next class. Here are some basics to help familiarize yourself with the table and help you to complete your assignment.

Metals are found on the left hand side The “staircase” shows metalliods Non-metals are on the right hand side

Each column is called a group/family Each row is called a period

Periodic Table Basics Page 7 Questions on page 8 and the “periodic table” you make will be handed in for marks. You have the rest of the class to work on it…… Let me know if you need help.
