Unit 1 Part 1: Atomic Theory
Essential Questions:
What is the composition of an atom?
What are the basic principles of atomic theory?
How did the modern concept of the atom begin, including different models of the atom?
How is the electron cloud organized in the modern model of the atom?
What are isotopes?
How are isotopes designated in hyphen and symbol notation?
How do you determine the number of protons, neutrons, and electrons given the designation of an isotope?
Describe the similarities and differences between the isotopes of an element.

Describe the similarities and differences between the isotopes of an element. How is average atomic mass calculated?
How is the electron cloud organized in the modern model of the atom?
Why is an understanding of the electron configuration important?
What are the rules for writing electron configurations?
What are the similarities and differences between electron configuration notation, orbital notation, and noble gas notation?
What is Lewis dot notation?
Compare inner shell and valence electrons.
GSE:
SC1. Obtain, evaluate, and communicate information about the use of the modern atomic theory and periodic law to explain the characteristics of atoms and elements.
a. Evaluate merits and limitations of different models of the atom in relation to relative size, charge, and position of protons, neutrons, and electrons in the atom.
b. Construct an argument to support the claim that the proton (and not the neutron or electron) defines the element’s identity.
c. Construct an explanation based on scientific evidence of the production of elements heavier than hydrogen by nuclear fusion.
d. Construct an explanation that relates the relative abundance of isotopes of a particular element to the atomic mass of the element.
e. Construct an explanation of light emission and the movement of electrons to identify elements.
f. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms (i.e. including atomic radii, ionization energy, and electronegativity).
g. Develop and use models, including electron configuration of atoms and ions, to predict an element’s chemical properties.
