These worksheets will help students complete the Lewis and Bohr structures for the first 20 elements. The included Periodic Table is simple and straightforward and assists students just beginning their studies in this area. Understanding the pattern of electron arrangement takes time and multiple activities to solidify for most students. These worksheets are a valuable addition to your teaching collection. As students continue their study of atoms, they need to give special attention to any electrons that are in an atom’s outer shell and these worksheets are a great starting point.
Use this to learn and reinforce answers to questions such as:
❑ How are electrons arranged in different atoms?
❑ How can electron arrangement be diagramed?
❑ How can the outer electrons of an atom be diagrammed?
Once students complete the worksheets they can capture their observations using the included Lab Notes or probing questions included in the instructions.
♦ Each element has a unique number of electrons.
♦ Different shells hold different amounts of electrons.
♦ The shells of atoms can hold increasing numbers of electrons.
