Unit Three:
Using
The Periodic
Table
- Knows
the structure and properties of matter
- Knows
how the electron configuration of atoms governs the chemical properties of
an element (SC.5.9-12.1)
- Identify
location and properties of four major groups of elements on the periodic
table (metals, metalloids or semiconductors, nonmetals, noble gases)
- Understands
how the elements are arranged in the periodic table, and how this
arrangement shows repeating patterns among elements with similar
properties. (SC.5.9-12.12)
- Trends
related to chemical reactivity, size of atoms, ionization energy, electron
affinity, valence electrons, and likely charge of ion.
- Relate
the basic properties of the alkali, alkaline earth, halogen and noble gas
groups
- The
seven elements that naturally exist as diatomic molecules (O2,
I2, N2, Br2, H2, F2,
Cl2) (Oh, I Never Bring Home
an F
from Class)
- Utilize
the periodic table to count atoms. This
involves understanding and working with the mole concept, atomic weight,
and Avogadro’s number (SC.5.9-12.12 and 12.13))
- Express
numbers in scientific notation
- Use
dimensional analysis in conversions
- Converting---
atoms to moles, moles to atoms, grams to moles, moles to grams, atoms to
grams, or grams to atoms (Be able to do the same for molecules)
Ongoing themes
- Understands
the nature of scientific knowledge
- Knows
that throughout history, diverse cultures have developed scientific ideas
and solved human problems through technology (SC.8.9-12.3)
- Knows
how basic research and applied research contribute to new discoveries,
inventions, and applications (SC. 8.9-12.5)
