Unit Information Atomic structure: 2003340 Chemistry 1 Quarter 1 Unit 3 atomic structure 7 instructional periods Standards SC.912.P.8.3: SC.912.P.8.4: Learning Goals and Scales Course Title 2003340 Chemistry 1 Measurement Topic Atomic structure Standards SC.912.P.8.3 SC.912.P.8.4 Scale Length 7 single class periods Learning Goal Learning Goal: I can explain the development of the Atomic Theory and I can describe the structure of the atom in terms of protons, neutrons and electrons. Score/Step 4.0 I know how atomic theory was developed and I can explain the different models of the atom and I understand the quantum atom. Score/Step 3.0 Target (Learning Goal) I understand atomic theory and the current model of the atom . Score/Step 2.0 I need help understanding the atomic theory and I do not know how it came to be. Score/Step 1.0 I need help understanding the atomic theory and I do not know how it came to be. Deconstructed Standards The student will be able to: Sequence the historical development of the atomic theory from Democritus through the Quantum Model. compare the atomic models in the historical development of Atomic Theory identify the deficiencies of each model and describe the new experimental evidence that led to later models describe the basic structure of an atom as a nucleus containing protons and neutrons surrounded by an electron cloud differentiate between protons, neutrons, and electrons on the basis of charge and relative mass. Overview An atom is the smallest particle of an element that retains the chemical properties of that element. As we continue to study matter and how it changes it is essential to understand the structure of the atom.

Vocabulary atom, atomic mass, atomic mass unit, atomic orbital, atomic theory, cathode ray, Dalton’s atomic theory, electron, isotope, mass number, neutron, nucleus, proton, quantum mechanical model Essential Questions What does an atom look like? Do you think we have discovered everything about atoms? Misconceptions The student may believe that … Particles possess the same properties as the materials they make up (copper atoms are “shiny and hard”). Particles are viewed as mini-versions of the substances they comprise.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
