Unit 1: Atoms, Atom Theory, & Periodic Table of Elements (August 15-September 22)

Standards:

• SC.8.P.8.7 (Level 1) – 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 sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons).
• SC.7.N.3.2 (Level 2) – Identify the benefits and limitations of the use of scientific models.
• SC.8.N.3.2 (Level 3) – Explain why theories may be modified but are rarely discarded.
• SC.8.E.5.10 (Level 3) – Assess how technology is essential to science for such purposes as access to outer space and other remote locations, sample collection, measurement, data collection and storage, computation, and communication of information

• Advanced: SC.912.P.8.4 – Explore the scientific theory of atoms (also known as atomic theory) by describing the structure of atoms in terms of protons, neutrons and electrons, and differentiate among these particles in terms of their mass, electrical charges and locations within the atom.
• SC.8.P.8.6 (Level 1) – Recognize that elements are grouped in the periodic table according to similarities of their properties.
• SC.6.N.2.2 (Level 2) – Explain that scientific knowledge is durable because it is open to change as new evidence or interpretations are encountered.
• Advanced: SC.912.P.8.5 – Relate properties of atoms and their position in the periodic table to the arrangement of their electrons.

• I am learning theories may be modified based on new evidence but are rarely discarded (in the context of atomic theory).
• I am learning to recognize that atoms are the smallest unit of an element and are composed of subatomic particles:
  •  Electrons (negative)-smallest subatomic particle, located outside of nucleus, does not figure into atomic mass, balances the negative charge with positive protons to make a neutral, stable atom
  •  Neutrons (neutral)-located in nucleus, mass of 1 AMU
  •  Protons (positive)-Located in nucleus, mass of 1 AMU, determines the Atomic Number, balances with electrons to obtain neutral, stable atoms
• I am learning to determine the type of subatomic particle using its location, mass, and charge.
• I am learning to create a model or diagram of an atom that contains a nucleus, an electron cloud, and subatomic particles.
• I am learning to discuss the benefits and limitations of various historical atomic models
• I am learning to explain electrons, protons and neutrons are parts of the atom and the nuclei of atoms are composed of protons and neutrons, which experience forces of attraction and repulsion consistent with their charges and masses.
• I am learning to recognize that elements are grouped in the periodic table according to similar properties

o Groups/Families- vertical columns of elements that share similar properties

o Periods-horizontal rows of elements with increasing atomic number

o Most elements on the periodic table are metals

o Metalloids are elements that have properties of metals and nonmetals

• I am learning to use the periodic table to identify and classify elements.
• I am learning to predict properties of an element using a periodic table when given information about other elements in the same column.
• I am learning to use the periodic table and electron configuration to determine an element’s number of valence electrons and its chemical and physical properties
• I am learning to explain how chemical properties depend almost entirely on the configuration of the outer electron shell
