Unit 08   Introduction to Atomic Theory

I understand that our understanding of science changes over time with the development of new observing and measuring technologies and continued experimentation.

Target 08-01 The student will describe the development of the atomic model and explain why models change over time.

“I can” Statements:

08-01 a: Explain how contributions made by the selected scientists changed the model of the atom.

08-01 b: Describe the model they designed including its strengths and limitations.

08-01 c: Explain why the atomic model has changed over time.

Target 08-02  The student will use the atomic model to predict the quantity, charges, masses, and locations of subatomic particles (protons, neutrons, electrons) including electron configuration and four quantum numbers.

“I can” Statements:

08-02 a: Compare the charges, locations, and relative masses of protons, neutrons, and electrons.

08-02 b: Calculate the numbers of protons, neutrons, and electrons in a neutral atom using atomic number and mass number.

08-02 c: Use a model of the atom including protons, neutrons, and energy levels (not including f orbitals) to diagram a neutral atom.

08-02 d: Using the Periodic Table, write the four quantum numbers for an electron.

08-02 e: Write an electron configuration for a neutral atom

Target 08-03 The student will use symbols and names for elements and isotopes.

“I can” Statements:

08-03 a: Create and interpret isotope notation and hyphen notation for atoms.

08-03 b: Create and interpret atom models for different isotopes.

08-03 c: Explain how an atom’s mass is determined (includes the definition of amu)

08-03 d: Explain the difference between the mass of an average atom and a specific nucleus.

Target 08-04 The student will use the Standard Model to explain the structure and forces within atoms.

“I can” Statements:

08-04 a: Use the Standard Model to describe the particles that make up the parts of the atom. (Quarks, Leptons, Force Carrier Particles)

08-04 b: Describe how each of the Four Fundamental Forces affect our everyday experiences. (Gravity, Electromagnetic, Strong Nuclear, and Weak Nuclear)

08-04 c: Rate the relative strengths and distances of action for the Four Fundamental Forces.

Target 08-05 The student will calculate moles from grams and grams from moles using dimensional analysis.

“I can” Statements:

08-05 a: Using dimensional analysis and funneling down, convert an amount in moles to grams.

08-05 b: Using dimensional analysis and funneling down, convert an amount in grams to moles.

08-05 c: Express answers with complete units including measurement unit and chemical ID.

08-05 d: Explain the difference between Avogadro’s number and molar mass.

Targets that are reemphasized:

Target 02-01 Explain the difference between scientific models, scientific theories, scientific laws, and scientific facts.

Target 02-03 Use math and graphs to analyze data.

Target 06-02 Use the alphabet of chemistry to name elements and write their symbols.
