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.
