2. A peek into the lives of our less reactive friends NOBLE GASES By Josh Allred

3. WHAT ARE NOBLE GASES? JOSH ALLRED CIS 1020 FINAL PROJECT

4. ALL NOBLE GASES Belong to group 8 on the periodic table Are naturally occurring Have very low chemical Reactivity At room temp are Gases Colorless Odorless Tasteless JOSH ALLRED CIS 1020 FINAL PROJECT

5. WHERE DO WE GET THEM? JOSH ALLRED CIS 1020 FINAL PROJECT

6. FRACTIONAL DISTILLATION Regular air is compressed and cooled to liquid state Subsequent mixture is slowly decompressed, which increases the temperature Different elements boil at different temperatures HeNeArKrXeRd JOSH ALLRED CIS 1020 FINAL PROJECT
