1) The document provides instructions for drawing Lewis structures to show ionic and covalent bonding between various elements. Students are asked to draw Lewis structures for pairs of elements, and indicate electron transfers or sharing to write chemical formulas. 2) For ionic bonds, students should draw Lewis structures, arrows to show electron transfer, charges for each ion, and chemical formulas. 3) For covalent bonds, the instructions are to draw Lewis structures, circles around shared electrons, bond structures, and chemical formulas.

1. Physical Science
Bonding Practice
Ionic Bonds – Draw the Lewis structures for each atom, draw arrows to show the transfer
of electrons, write the charge for each ion, and then write the chemical formula
1. Calcium and Flourine 2. Magnesium and Sulfur
3. Calcium and Oxygen 4. Magnesium and Chlorine
5. Sodium and Flourine 6. Aluminum and Oxygen
Covalent Bonds – Draw the Lewis structure for each atom, draw circles to show the
electrons that are shared, and then write the bond structure and chemical formula
