  1. Atomic Structure

  2. Parts of an atom Nucleus Electrons Electron Clouds Electron Shells Protons Neutrons

  3. Protons 3 Li Lithium Located in the nucleus Positive Charge + Mass: 1 amu + + Nucleus + The number of Protons is always the SAME as the atomic number Mass = 3 amu

  4. Protons How many protons does an atom of Carbon have? The atomic number is 6 Carbon has 6 protons 6 C Carbon 12.0 The number of Protons is always the SAME as the atomic number

  5. Protons How many protons does an atom of Oxygen have? How many protons does an atom of Titanium have? 8 O Oxygen 16.0 The number of Protons is always the SAME as the atomic number 22 Ti Titanium 47.9 The number of Protons is always the SAME as the atomic number

  6. Neutrons Located in the nucleus NO charge (nuetral) Mass: 1 amu 0 0 Nucleus 0 Mass = 3 amu

  7. Atomic Mass 0 + Nucleus 0 + 2 Protons + ?? Neutrons Mass 4.0 2 Neutrons Protons 2 He Helium 4.0 Atomic Mass = Protons + Neutrons

  8. Atomic Mass + + 0 + 0 Nucleus + 0 0 + 0 5 Protons + ?? Neutrons Mass 11 0 6 Nuetrons Protons 5 B Boron 10.8 11 Atomic Mass = Protons + Neutrons

  9. Atomic Mass 8 O Oxygen 16.0 How many protons does Oxygen have? What is the atomic Mass of Oxygen? How many neutrons must it have? How many protons does Titanium have? What is the atomic mass of Titanium? How many neutrons must it have? 22 Ti Titanium 47.9 48
