1. Oxygen has 8 protons, 8 neutrons, and 8 electrons. What is the atomic number of oxygen? What is its atomic mass? 2. Draw an Oxygen atom. 3. Draw a Nitrogen atom (atomic number is 7; atomic mass is 14). 4. Draw a Hydrogen atom. 5. What kind of bond would you get if you have a Nitrogen atom and Hydrogen atoms? How may hydrogen would you need for Nitrogen to be balanced? 6. What kind of bond would you get if you have a Carbon atom and Hydrogen atoms? How may hydrogen would you need for Carbon to be balanced? 7. Draw a sodium atom (atomic number is 11; atomic mass is 23) 8. Draw a chlorine atom (atomic number is 17; atomic mass is 35) 9. What kind of bond would you get between Chlorine and Sodium? 10. Create the atoms and bonds using the 3D models. Take pictures to show me. (You do not have this as I have the models for my students in class, but if you happen to have playdouch or come up with some other creative way of doing it like candies or Lego, go for it) 11. Put these solutions in order from acidic to basic (from more acidic to more basic) Lemon juice=2.3 Blood= 7.4 Soap = 11 Bleach=13 Coffee = 5 Gastric Juices = 1 Backing soda = 8 Drain cleaner = 14 Milk = 6.7 Egg white = 8 Urine = 5 Pure water = 7 Tomato juice = 4.3 12. List the solutions into acidic and basic? Acidic Basic 13. How many more or less H+ does Urine have compared to Pure Water? 14. How many more or less H+ does Urine have compared to Gastric Juices? 15. How many more or less H+ does Coffee have compared to Bleach? Which one is more acidic and which one is more basic? 16. Draw what happens to table salt when you dissolve it in water.
