Honors Chemistry Unit 2: Atomic Theory & Periodic Table

Science

SC.912.P.8.3 . Explore the scientific theory of atoms (also known as atomic theory) by describing changes in the atomic model over time and why those changes were necessitated by experimental evidence.

Cognitive Complexity Rating: Level 3: Strategic Thinking and Complex Reasoning Strand

Chemistry Prior Grade(s): Science Connection

SC.912.P.8.1Explore the scientific theory of atoms (also known as atomic theory) by using models to explain the motion of particles in solids, liquids, and gases.

SC.912.P.8.7 Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of subatomic particles (electrons surrounding a nucleus containing protons and neutrons).

Content Limits

8.3- Describe the development and historical importance of atomic theory from Dalton (atomic theory), Thomson (the electron), Rutherford (the nucleus and “ gold foil experiment), and Bohr (planetary model of atom), and understand how each discovery leads to modern atomic theory.

Access PointsIndependentSC.912.P.8.In.3: Identify the nucleus as the center of an atom.

SupportedSC.912.P.8.Su.3: Recognize that atoms are tiny particles in materials, too small to see.

ParticipatorySC.912.P.8.Pa.3: Recognize that the parts of an object can be put together to make a whole.

ScienceSC.912.P.8.5

Relate properties of atoms and their position in the periodic table to the arrangement of their electrons.

Grade(s): Science ConnectionSC.8.P.8.4Classify and compare substances on the basis of characteristic physical properties that can be demonstrated or measured for example, density, thermal or electrical conductivity, solubility, magnetic properties, melting and boiling points, and know that these properties are independent of the amount of the sample.

SC.8.P.8.5Recognize that there are a finite number of elements and that their atoms combine in a multitude of ways to produce compounds that make up all of the living and nonliving things that we encounter. 

SC.8.P.8.6Recognize that elements are grouped in the periodic table according to similarities of their properties.
