  1. Atomic Theory HOT SEAT!!!! Chem 332 – O’Dette

  2. What atomic model did Thomson establish? You must also draw a picture of the model! Plum Pudding Model

  3. What was Rutherford’s two main discoveries? • Atom is mostly empty space • Large positive nucleus

  4. List the weight, charge, and location of the three parts of an atom. • Proton = 1 amu, positive, nucleus • Neutron = 1 amu, neutral, nucleus • Electron = 0 amu, negative, outside nucleus

  5. What are electron configurations? • Electron configurationsdefine the location of the electrons in an atom.

  6. What is the electron configuration for Ni? 1s22s22p63s23p64s23d8

  7. An atom of carbon, C, has 6 protons and 6 neutrons. What is it’s mass number? 12

  8. An atom has 53 neutrons, 53 protons, and 53 electrons. What is the atomic number and element symbol for this atom? 53; I

  9. What is the nuclear symbol for the isotope of mercury(Hg) with 120 neutrons?

  10. What is the atomic mass for nitrogen given the information below? You must show your work to receive credit!!! (14)x(.9963) + (15)x(.0037) = 14.007

  11. What is the symbol for the ion with 34 protons and 36 electrons? Se-2
