Lewis Structures

In this Lewis structures learning exercise, students identify and describe what Lewis structures or dot diagrams are and how they illustrate the valence electrons in an outer shell. Then they use a periodic table to determine the numbers of valence electrons for each of the 20 elements given. Finally, students draw a dot to represent each valence electron around the element symbol, following the pattern to position number 1.

Lesson Planet helps me search from such a large variety of creative and innovative teaching ideas from dedicated teachers. I am always looking for ideas to better teach my students and solicit the help of others in the education field. Many of the lessons guide students from concrete to abstract learning. Keep up the great work!
