  1. 1What is the charge of a ProtonPositive!
  2. 2What is the charge of a Electron?Negative!
  3. 3What is the charge of a Neutron?Charge, what charge?
    It has NO charge
    Neutron = Neutral
  4. 4Where is the Proton located in an atom?In the Nucleus
    (In the INSIDE) - yep, just hanging out in the inside...
  5. 5Where is the Neutron located in an atom?In the Nucleus
    On the Inside - yep, just hanging out on the inside man....
  6. 6Where is the Electron in an atom?On the OUTSIDE!....yea, those CRAZY electrons, just go round and round the outside! The further away from the nucleus, the more energy the atom has!
  7. 7Where can we find the atomic number of an element?oh yea, show me!
  8. 8What does the atomic number of an atom tell you?It tells you how many protons an element has
  9. 9Are the number of Protons and Electrons always the same?YES!
    they pretty much balance each other out, so the number of protons always = the number of electrons. They are like the husband and wife of an atom :)
  10. 10What does the atomic mass of a number tell you?It tells you how many Protons and how many Neutrons are in an atom
  11. 11Let's look at Potassium on the periodic chartok
    :)
  12. 12What is Potassium's Element symbol (look on the chart)ok
    :)
  13. 13What is Potassium's atomic number? (look on the chart)ok
    :)
  14. 14What does Potassium's atomic number tell you?It tells you how many Protons Potassium has
  15. 15If we know the number of Protons an element has, how many Electrons must it have?The same number
  16. 16What is Potassium's Atomic Mass? (look at the chart)ok
    :)
  17. 17What does the atomic mass of Potassium tell us about the protons and the neutrons?it tells us how many protons and neutrons the element has
  18. 18If you wanted to find out the number of neutrons of Potassium, what math problem would you use to do that?Since the atomic number of Potassium really means the number or protons potassium has, I would do this: take the atomic mass of potassium-the atomic number of potassium = number of neutrons in potassium
  19. 19Find element number 3 in the periodic tableok
    :)
  20. 203 LI is the elements what?Symbol
  21. 213 LI "Lithium" is the what of the elementThe name
  22. 223 LI The atomic mass of Lithium is what?6.9
  23. 23Draw a picture of Lithiumok
    :)
  24. 24How can we find the number of protons by looking at a picture of Lithium that you just drew?By counting the number of protons or plus signs (positive charge) in the nucleus
  25. 25How can we find the number of electrons by looking at the picture of Lithium you just drew?By counting the number of Electrons around the nucleus
  26. 26If you aren't told how many electrons an element has but you know the number of protons the elements has, how can you find out the number of electrons?I know that the number of electrons = the number of protons. That's how I know the number of electrons
  27. 27How can we find the number of neutrons an element has?Just subtract the atomic number (the number at the top) from the atomic mass (the number at the bottom)
  28. 28Find Iron on the Periodic Tableok
    :)
  29. 29what is Iron's symbol? What is Iron's Atomic Number? What is Iron's Atomic Mass? What is Iron's number of Protons? What is Iron's number of Neutrons? What is Iron's number of electrons?ok
    :)
  30. 30Draw a picture of Ironok
    :)
  31. 31What is the rule about the first letter in an element's symbol?Capitalize it
  32. 32What is the rule about the second letter in an elements symbol?make it lower case
  33. 33The first energy level of an atom can hold how many electrons? draw a picture2
  34. 34The second energy level of an atom can hold how many electrons? draw a picture8
  35. 35The third level of an atom can hold how many electrons? draw a picture?18
  36. 36Show me Potassium on the periodic table that has the energy level (19) Tell me how many energy levels it has and how many electrons in each energy levelok
    :)
  37. 37Electrons with the least energy are located where?In the inner shell
  38. 38Electrons with the most energy are located where?In the outer shells
  39. 39The outermost shell can gain, lose or share electronsok.
    Those crazy electrons
  40. 40A neutral atom is what?an atom that has an equal number of electrons and protons
