Chapter 5/6 Test Review
Know the 4 models of the atom and how each is different from the one before… plum pudding nuclear planetary electron cloud
Know the 4 models of the atom and how each is different from the one before… How is Thomson’s model different from Dalton’s ideas ? How is Rutherford’s model different from Thomson’s model ? How is Bohr’s model different from Rutherford’s model ? How is the modern atomic model different from Bohr’s model ? Why was Rutherford and Bohr’s models “limited” ?
Know these people and what they contributed to atomic theory… DaltonHeisenberg ThomsonMendeleev Rutherford Bohr Schrodinger
Rules for electron configuration and the four blocks on the periodic table… Write electron configurations, valence and noble gas notations for given elements Aufbau principle, Pauli exclusion principle, Hund’s rule S-block, p-block, d-block, and f-block and why they are called this
Understand the following things related to the quantum mechanical model… The role of light Quantas (of energy), ground state, excited state Quantum energy levels Orbitals Schrodinger’s equation and Heisenberg’s uncertainty principle
Describe the difference between the electron cloud model and the quantum mechanical model… What does the quantum mechanical model describe? What is the electron cloud model and what does it look like? Why is there “uncertainty” built into the model?
Understand the role of Mendeleev and the organization of the periodic table… How did Mendeleev originally organize his periodic table? How is the modern periodic table organized? Difference between periods and families? Relationship between family numbers and valence electrons?
Understand the formation of ions and why atoms form ions… stability/noble gas configuration cation formation and resulting charges anion formation and resulting charges
Understand the trends and the cause and effect relationships in the periodic table… atomic radiusacross periods? ionic radiusacross rows? ionization energy electronegativityhow are # protons and # of shielding effectquantum levels related to all of these trends???
