• The electrons in metals can be thought of as being property of all the atoms.
• The positive nuclei are surrounded by a "sea of electrons" that are all attracted by the nuclei at the same time.

PowerPoint is a "presentation graphics" program. It is used to visually provide information to a group of people - not just one person sitting in front of a computer. Color combinations and font size must make the slides easily read from a distance.

1. Use a new PowerPoint slide with the layout that has a title block and a blank page.
   1. Title this slide as "The 7 Diatomic Molecules".
   2. Paste this Periodic Table  onto the slide.
   3. Put a size 4 green line around the box on the table containing each of the diatomic molecules.
2. Use a second PowerPoint slide with the same layout as #1.
   1. Title this slide as "Ionic Bonding".
   2. Use PowerPoint tools to draw a Bohr model of a hydrogen atom on the left of the slide and a Bohr model of a chlorine atom on the right.
   3. Duplicate this slide. Then use motion on the new slide to show what happens to the electron of the hydrogen atom when the compound HCl is formed.
