Author: Sarah Kummeth
Description:

-Learn how to draw a Lewis Dot Diagram for a representative element.
-Understand the differences between electron pairs and unpaired electrons.

In this packet you will go step by step to learn how to diagram a representative element using a lewis dot diagram structure. We will also go over the differences between unpaired and paired electrons.

Terms to Know

 

  1. Lewis Dot Diagram: A representation of a molecule, ion or formula unit through use of the atomic symbol and coordinating valence electrons of an element
  2. Unpaired Electron: One electron that occupies an orbital all on its own.
  3. Electron Pair: Two electrons that occupy the same orbital, but spin in opposite directions. The goal of a Lewis Dot Diagram is to have four of electron pairs.

Steps to Drawing a Lewis Dot Diagram for Representative Elements

Valence Electrons

Remember that even if an element is in lower periods, the group number is what determines the valence electrons. The number of valence electrons does not vary by period. It is the same going top to bottom. (Besides Hydrogen and Helium)
